What is it called that there are negatively charged electrons inside an atom, an atom is electricall

Ionic compounds are chemical compounds made up of cations and anions. When active metals (such as sodium, potassium, calcium, magnesium, etc.) and active nonmetals (such as fluorine, chlorine, oxygen, sulfur, etc.) are combined with each other, the active metals lose electrons to form positively charged cations (such as Na+, K+, Ca2+, Mg2+, etc.), and active nonmetals obtain electrons to form negatively charged anions (such as F-, Cl-, O2-, S2-, etc.), and cations and anions form ionic compounds by electrostatic action. For example, sodium chloride is an ionic compound composed of positively charged sodium ions (Na+) and negatively charged chloride ions (Cl-).

Many bases (e.g., NaOH, KoH, Ba(OH)2, etc.) and salts (e.g., CaCl2, Kno3, CuSO4, etc.) are ionic compounds. In ionic compounds, the total number of positive charges carried by cations is equal to the total number of negative charges carried by anions, and the whole compound is electrically neutral. Most ionic compounds do not conduct electricity in their solid (or crystalline) state, while they do in an aqueous solution or in their melted state.

Generally speaking, ionic compounds have higher melting and boiling points, greater hardness, brittleness, difficult compression, and difficult volatilization.

Some basic oxides, such as Na2O, K2O, common salts such as NaCl, KF, and common bases, such as NaOH, are ionic compounds.

Ionic compounds are compounds that exist between 1. active metals (referring to the metallic elements of the first and second main groups) and active non-metallic elements (referring to the elements of the sixth and seventh main groups). 2. Compounds formed between metal elements and acid ions. (Acid ions such as sulfate ions, nitrate ions, carbonate ions, etc.) 3, between ammonium ions (NH4+) and acid ions, or between ammonium and non-metallic elements covalent compounds exist between non-metallic elements, for compounds formed by two elements.

If there is a non-polar covalent bond between the same non-metallic elements, if there is a polar covalent bond formed between different elements, they are all covalent compounds.

Ionic compounds are electrolytes and can conduct electricity in both aqueous and molten states. Role in galvanic cells: Forming a closed circuit!

Relationship between ionic compounds and covalent compounds.

Both ionic and covalent compounds involve the movement of electrons.

Ionic compounds are compounds formed by ionic bonds, which are formed by the transfer of electrons (cations for those who lose electrons and anions for those who gain electrons). That is, the chemical bond formed between the positive and negative ions due to the electrostatic attraction.

Covalent compounds are compounds formed by covalent bonds composed of shared electrons, covalent bonds are a kind of chemical bonds, two or more atoms use their outer electrons together, and ideally reach a state of electron saturation, thus forming a relatively stable and strong chemical structure called covalent bonds. Unlike ionic bonds, atoms that enter the covalent bond do not show electrical properties outwards because they do not gain or lose electrons. The strength of the covalent bond is stronger than the hydrogen bond and is not much different from the ionic bond or even stronger than the ionic bond.

Matter is made up of atoms, which are made up of a positively charged nucleus (made up of protons and neutrons, which are actually positively charged) and negatively charged electrons that are constantly moving around them.

If there are the number of electrons around, there will be the same number of protons in the nucleus, and different numbers of protons will represent different substances.

These courses will be taken in high school physics.

An atom is the smallest unit that an element can exist.

are the smallest particles in chemical change. The bright suspect atom is made up of the nucleus.

and extranuclear electrons. The proto-Shen code nucleus is composed of protons and neutrons. In a chemical reaction, only the electrons outside the nucleus change, but the composition of the nucleus does not change. in nuclear reactions.

, the nucleus of the atom changes, and the atom becomes the atom of other elements.

There are only two types of electricity that exist in nature. It is stipulated that the point of the glass rod that has been rubbed with silk is called positive electricity, which is represented by the symbol "+"; The electricity carried by a rubber rod rubbed with fur is called negative electricity, which is represented by the symbol "—".

Positive charge is made up of a positive charge.

produced, in the atom, are the protons that make up the nucleus; Negative electricity is generated by a negative charge, which in an atom is an electron outside the nucleus. In layman's terms, you can think that the reason why the glass rod rubs the silk to produce a positive electricity and the rubber rod rubs the fur to produce a negative electricity. In atoms with wide bonds, the positively charged nucleus has an attraction effect on the negatively charged electron, but the attraction ability of different nuclei to electrons is different.

Therefore, the nucleus of the atom in the glass rod has a weaker ability to attract electrons than the nucleus in the silk, so when the glass rod rubs the silk, the electrons run towards the silk, making the glass rod positively charged (in fact, at the same time, the silk is negatively charged). The same reasoning has been explained that the rubber rod is negatively charged after rubbing the fur.

The same kind of electricity repells each other, and different kinds of electricity attracts each other.

According to the color dynamics of the orange mold, the atom is composed of protons, neutrons, and electrons, of which protons and neutrons are collectively called"Hadrons", each of them is composed of three "quarks", and the "quarks" also maintain the force by exchanging rubber particles, which are called "gluons".

Basically, protons and neutrons are also electrons, electrons are negatively charged, neutrons are uncharged, and protons are positively charged.

1. Introduction

1. Atoms are the smallest particles that cannot be separated from chemical reactions. A positive atom contains a dense nucleus and a number of electrons that are negatively charged around the nucleus. Whereas, the nucleus of a negative atom is negatively charged, and the surrounding electrons are positively charged.

The nucleus of a positive atom is made up of positively charged protons and electrically neutral neutrons.

2. The antiprotons in the nucleus of the negative atom are negatively charged, thus making the nucleus of the negative atom negatively charged. When the number of protons is the same as the number of electrons, the atom is electrically neutral; Otherwise, it is a positively or negatively charged ion.

3. According to the number of protons and the number of atoms, the types of atoms are also different: the number of protons determines which element the atom belongs to, while the number of neutrons determines which isotope the atom is of this element. Atoms constitute molecules, and the same kind of electric charges in the molecular constituent substances repel each other, and different kinds of electric charges attract each other.

II. Definitions. The smallest particles in chemical change. Note:

Atoms are the smallest particles that make up matter. No, atoms can be divided into nuclei and extranuclear electrons, and the nucleus is composed of protons and neutrons, and the number of protons is the basis for distinguishing different elements of various chain-lossing potatoes. Protons and neutrons can continue to be divided.

So atoms are not the smallest particles that make up matter, but atoms are the smallest particles in chemical reactions.

Atoms are uncharged, and electrons are negatively charged; There are protons and neutrons inside the nucleus, protons are charged, neutrons are not charged, the density of the nucleus is extremely large, and the electron mass is extremely light and generally negligible. The volume of an atom is determined by the number of outer electron layers, and the mass is determined by the number of neutrons and protons in the nucleus.

Which proton is the size + proton = nucleus.

Nucleus + electron = atom.

According to the quark model, quarks are fractionally charged, with each quark having a +2 3e or -1 3e charge (e is the proton charge unit macrovertical).

A neutron consists of two lower quarks and one upper quark, and since the upper quark has a +2 3e charge and the lower quark has a -1 3e charge q=-1 3e*2+2 3e=0, the neutron is not charged.

A proton is composed of two upper quarks and one lower quark, and since the upper quark has a +2 3e charge, the lower quark has a -1 3e charge, and 2 3e*2-1 3e=e, the proton has a positive charge.

An atom is not electrically charged! But in which the nucleus is positively charged! Whereas, electrons outside the nucleus are negatively charged. The positive and negative charges of atomic bands are equal!

Atoms are positively charged, and electrons are negatively charged.

The atomic nucleus is divided into protons and neutrons, in which the nucleus is positively charged or electrons, and the electrons are negatively charged, and the electricity they carry is equal and the electricity is opposite;

So the answer is: nucleus; Electron.

An atom is made up of a nucleus and a nucleus is made up of and , where is positively charged.

The atom is made up of the nucleus and the electrons outside the nucleus The nucleus is made up of positively charged protons and uncharged neutrons So the answer is: electrons outside the nucleus; Proton; Neutron; Proton;

A molecule is made up of atoms, and atoms are made up of electrons and , where the positively charged, negatively charged nucleus is made up of the sum of electrons

1) Atoms are composed of nuclei and electrons, in which electrons are positively charged, and prototalc subnuclei are composed of protons and neutrons, protons are positively charged, and neutrons are not charged; Since the negative charge of the electron is equal to the positive charge of the proton, the atom is normally not electrically charged; (2) The universe is also composed of matter, the universe is a hierarchical celestial system, and most scientists believe that the universe originated from a large ** about 13.7 billion years ago; Therefore, the answer is: the nucleus; Nucleus. Electron. Proton; Neutron; Neutron; Large**

Does positive charge refer to a positively charged proton or an atom that has lost its electrons but still has electrons? 100 points.

If the atom gets electrons, then the number of electrons is greater than the number of protons in the nucleus, the number of positive charges in the atomic belt is greater than the number of negative charges, and the atom is negatively charged externally; If the atom loses electrons, then the number of electrons is less than the number of protons in the nucleus, the number of positive charges in the atomic belt is less than the number of negative charges, and the atom is positively charged externally.

Charge is the name given to a substance that is charged: the electric nucleus is the electron core of the charged body.
