    An atom is made up of electrons moving at high speed outside the nucleus and outside the nucleus. The nucleus is composed of protons and neutrons (not divided into two layers) each proton has a unit positive charge, neutrons are not electrical, there are as many protons as there are units of positive charge, the number of positive charges carried by protons is called the number of nuclear charges, the number of nuclear charges = the number of protons = the number of electrons outside the nucleus. Reference.

    The number of charged nuclei = the number of protons (protons with dots, neutrons are not charged) = the number of electrons outside the nucleus (not charged externally).

    The number of nuclear charges refers to the number of atomic numbers, and there are several nuclear charge numbers.

    The nuclear charge number is that an atom is made up of electrons moving at high speed outside the nucleus and outside the nucleus.

    The nucleus is composed of protons and neutrons (not divided into two layers), each proton has a unit positive charge, the neutron is not charged, there are as many protons as there is a unit positive charge, and the number of positive charges carried by protons is called the number of nuclear charges.

    The number of nuclear charges === the number of protons in the nucleus, it is often said that the "nuclear charge number" of the oxygen atom is 8, that is, the proton number of the oxygen atom is 8, the atomic number of the oxygen element is 8, and the number of electrons outside the nucleus of the oxygen atom is 8

    This is because each electron has a negative charge of one unit, and the whole atom is invisible, i.e., electrically neutral, so the number of nuclear charges must be equal to the number of electrons outside the nucleus.

    Number of nuclear charges = number of protons in the nucleus.

    The electrons in the atom have a negative charge, and the proton has a positive charge, and the nuclear charge number refers to the number of the nuclear charge of the nucleus, which is taken as an absolute value, which is equal to the number of protons.

    The number of nuclear charges is the number of charges carried by the nucleus, the atom is composed of the nucleus and the electrons outside the nucleus, there are protons and neutrons in the nucleus, a proton has a positive charge of one unit, and the neutron is not charged, so the number of charges carried by the nucleus is the number of protons in the nucleus, that is, the number of nuclear charges = the number of protons.

    There is a difference between nuclides and elements. An element is a general term for the same class of atoms with the same number of protons, and a nuclide is an atom with a certain number of protons and a certain number of neutrons, each element has one or two or more nuclides, and now there are 109 known elements and more than 2,000 known nuclides. There is also a difference between nuclides and isotopes.

    An isotope is an atom of the same element that occupies the same position in the periodic table with the same number of protons and a different number of neutrons, while a nuclide is an atom with the same number of protons and the same number of neutrons.

    Number of nuclear charges= number of protons = number of electrons outside the nucleus =Atomic number(The number of electrons outside the nucleus should be removed in the ion) the number of protons + the number of neutrons =Relative atomic mass= mass.

    In an atom, the number of nuclear charges is equal to the number of protons, which is equal to the number of electrons outside the nucleus. Nucleus.

    It is made up of protons and neutrons, each of which carries a unit of positive charge.

    There are as many units of positive charge as there are protons, and the number of positive charges carried by protons is called the number of nuclear charges.

    Structure:

    Atoms are made up of the nucleus and electrons outside the nucleus. And the periodic table.

    The arrangement is based on the number of nuclear charges, that is to say, the atomic number is determined by the number of nuclear charges, so the atomic number is the number of nuclear charges. In general, atoms are not electrically charged and are neutral. At this point, the positive charge is equal to the negative charge, the proton in the nucleus has a positive charge, and a proton has a positive charge of one unit.

    In this way, the number of nuclear charges is equal to the number of protons in the nucleus, and the electrons outside the nucleus have a negative charge, which is also an electron with a unit of negative charge, so the number of protons in the nucleus is equal to the number of electrons outside the nucleus. In this way, the atomic number, the number of nuclear charges, the number of nuclear charges, the number of protons in the nucleus, the number of protons in the nucleus, the number of electrons outside the nucleus, and the number of electrons outside the nucleus can be obtained by substituting the same amount to obtain the "atomic number, the number of nuclear charges, the number of protons in the nucleus, and the number of electrons outside the nucleus".

    Number of nuclear charges = number of protons = number of electrons outside the nucleus = number of atomic numbers (the number of electrons outside the nucleus should be removed from the ion) number of protons + number of neutrons = relative atomic mass = mass number. The nucleus is a dense ball that concentrates most of the mass of an atom and has a positive charge, which is the opposite of electron.

    An atom is made up of electrons moving at high speed outside the nucleus and outside the nucleus. The nucleus is composed of protons and neutrons (except for the proton, the nucleus has only protons, no neutrons) (not divided into two layers) Each proton has a unit positive charge, neutrons are not electrically charged, and there are as many protons as there are positive charges, and the number of positive charges carried by protons is called the nuclear charge number.

    Details:

    Atoms are the smallest particles that cannot be redivided into 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 negative electrons are positively charged.

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

    The antiproton in the nucleus of the negative atom becomes 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.

    Depending on the number of protons and neutrons, the type of atom is different: the number of protons determines which element the atom belongs to, while the number of neutrons determines which isotope the atom is of that element. Atoms make up molecules, and the same kind of charges repel each other in the molecules that make up the substance, and different kinds of charges attract each other.
