Are the chemical properties of molecules and atoms of the same element the same?

The chemical properties of molecules and atoms of the same element are the same

First of all, we must know what an element is, and the same class of atoms with the same number of nuclear charges (i.e., the number of protons) is collectively called an element. So the elements are listed on the periodic table, and you ask sulfur monoxide and sulfur dioxide, these cannot be said to be elements, only different substances made up of the same elements. As for carbon and carbon-60, although there are many types of carbon in terms of physical properties, the chemical reactions (i.e., chemical properties) are all reactions of element C, so the chemical properties are the same.

Second, a molecule can be composed of many elements, but the chemical properties are reflected in the chemical reaction, reflected in the chemical formula, and if the chemical formula is the same, the chemical properties must be the same. So there is the previous "molecules and atoms of the same element have the same chemical properties. Conclusion.

No. Sulfur dioxide and sulfur monoxide are different substances. Carbon and carbon-60 are the same substance, but the particle arrangement is different, and the chemical properties are naturally the same If you understand, there is labor.

The chemical properties of the molecules are the same, but they are different for the compounds.

Sulfur monoxide and sulfur dioxide are two substances so so2, so the chemical properties are different.

C and C60 are two structures of the same substance, so the chemical properties are the same.

Flip through the book carefully, there is the answer in the book.

The chemical properties of an element are closely related to the outermost electrons of an atom.

The structural formula is a chemical formula that uses element symbols and ** to indicate the arrangement and binding of atoms in the molecules of a compound (or element), and is a simple way to describe the structure of a molecule. The structural formula can completely map the chemical bonds between each atom within the molecule.

A simple structural formula is a simple expression of a structural formula (with carbon-hydrogen bonds omitted). The simple structure usually includes two parts: hydrocarbon group and functional group. At the same time, structures that are closely related to the properties of organic matter, such as carbon-carbon double bonds and carbon-carbon triple bonds, should not be simplified.

Notes:

The simple structure is an abbreviated form of expression after omitting the single bond in the structural formula, and is usually only applicable to pure substances in molecular form.

The writing rules of the simple structure: the functional groups in the substance should be expressed, as long as the carbon-hydrogen single bond is omitted, and most of the single bonds such as carbon-carbon single bond, carbon-chlorine single bond, carbon and hydroxyl single bond can be omitted or not.

The necessary condition for the correct writing of the structure is to truly grasp the meaning and writing method of the plane structure. Therefore, from the beginning of contact with the structure of organic compounds, it is necessary to pay attention to laying this foundation.

1. From a microscopic point of view, atoms and molecules are particles that make up matter. Molecules, in turn, are made up of atoms.

2. From a macroscopic point of view, matter is made up of elements.

3. The chemical formula is a formula that uses a combination of element symbols and numbers to represent the composition of pure substances.

The chemical similarity of atoms is determined by the number of electrons in the outermost shell.

The number of outermost electrons is less than (or equal to) 3, such as alkali metal and alkaline earth metal elements, it is easy to lose the outermost electrons and reach a stable structure of the outermost 8 electrons, which makes it have strong metallicity and reducibility. However, this does not apply to subgroup elements, such as gold and silver, which have 1 electron in the outermost shell, and mercury in the outermost shell with 2 electrons, but they are both inactive.

The number of outermost electrons is more than (or equal to) 5, such as halogen and oxygen elements, and it is easy to obtain electrons to reach the stable structure of the outermost 8 electrons, which makes it have strong non-metallic and oxidizing properties.

The chemical properties of an atom are most closely related to the number of electrons in its outermost shell. For example, the number of outermost electrons of nitrogen and phosphorus atoms is 5, so their chemical properties are similar; The outermost electrons of carbon and hydrogen are 4 and 1, respectively, but they are half of the outermost electron-stable structure, so their chemical properties are also similar. But the number of outermost electrons of the helium atom is 2, and the number of outermost electrons of the magnesium atom is also 2, because the outermost electrons of the helium atom have reached a relatively stable structure, the outermost electrons of the magnesium atom are volatile, so their chemical properties are not similar.

The chemical properties of an element are mainly determined by the number of electrons in the outermost shell.

The outermost shell has the same number of electrons and similar chemical properties.

Note that H and HE are exceptions.

In the schematic diagram of the structure of an atom, the number of outermost electrons can reflect its chemical properties, and generally the outermost electron number is the same, that is, it has similar chemical properties, but it should be distinguished from special elements

It has to do with the electron configuration, especially the number of electrons in the outermost shell.

It is determined by the intrinsic structure of its atoms, protons, etc.

From the structure of the atom itself, otherwise the groups of the periodic table, how can the periodic elements have a pattern.

The same molecule has the same chemical properties - gaseous iodine, liquid iodine, and solid iodine are all made up of iodine molecules (the same molecule), and they all make starch blue (chemically identical).

Different substances have different molecular properties – hydrogen is made up of hydrogen molecules, while nitrogen is made up of nitrogen molecules – the molecules of the two are different.

Hydrogen can burn, while nitrogen can't – the two have different chemical properties.

This question is an interpretation of the sentence in the textbook that "the particles that maintain the chemical properties of matter are molecules". The molecules are different, and of course the chemical properties are different.

The same kind of molecule has the same chemical properties, and different kinds of substances have different molecular properties, which should be understood as follows: the structure of the molecule determines the chemical properties, the same kind of molecular structure is the same, so the chemical properties are the same, and the molecular structure of different kinds of substances is different, so the properties are different.

The same molecule is the same substance, and of course the chemical properties are the same.

Different atoms have different proton numbers, so the species are different, and hence the properties are definitely different.

For example, iron atoms make up the metal iron, and aluminum atoms make up the metal aluminum. Iron and aluminum are two different substances, so their properties are also different.

This is due to the fact that the atoms that make up the matter are different, which means that the properties of different atoms are different. But since they are atoms and have the same characteristics in structure, the outermost electron number is less than 4, and they all belong to metal atoms, so they also have some similarities in nature. For example, they all have metallic luster, good electrical and thermal conductivity, and so on.

But in terms of these natures, they are also completely different.

That's right. The molecular properties of the same substance are the same, for example, the water molecule in China and the water molecule in the United States are both water molecules, and of course the properties are the same.

Different substances have different molecular properties, such as carbon dioxide and oxygen, and of course the properties of the two are different.

In the junior high school context, there are three types of elementary particles that matter is made of: molecules, atoms, and ions. They are similar in nature.

1. They are all in constant motion;

2. There are gaps between them;

3. They all have mass, volume, but they are small.

4. The properties of the same kind of particles are the same, and the properties of different kinds of particles are different.

Therefore, the molecular properties of the same substance are the same, and the properties of the atoms of the same substance are also the same.

This is a conceptual problem, just look at the introduction of these three substances in the textbook!

Generally speaking, molecules and ions are made up of atoms (as for what atoms are made of, I won't be busy explaining them for the time being)!

So how do we tell them apart?

If this substance is composed of a single particle (particles: atoms, molecules, ions can be said to be particles), then it can be said to be composed of atoms, such as: iron, carbon and other metals!

If it's not made of a single particle, it could be a molecule or an ion!

The difference between molecules and particles is whether they have an electric charge or not, that is, whether they gain (or lose) electrons, and if they gain (or lose) electrons from the outside world, then they are ions, otherwise they are molecules!

molecules (noble gases are also made up of one atom, but they are special, so they are also monoatomic molecules).

How do we know which ions an ionic compound is made of?

First of all, after it is ionized in the solution, it will produce a lot of anion and cation, such as you said: sulfuric acid molecule, it is in the solution, after ionization, it will produce hydrogen ions and sulfate ions, but will not produce hydroxide ions and other ions, and other ions are ionized in the solution.

Answer welcome your inquiry, I am the answer for you, has helped more than 4,000 people, your question I have seen, is currently sorting out the answer for you, please wait a while

Molecules are made up of atoms. Molecules, atoms, and nineteen states of matter, and elements are analyzed in terms of the macroscopic state of matter.

For example, ozone and oxygen: the smallest particle that retains its ozonomic properties is the ozone molecule O3, not the oxygen atom. The smallest particle that also maintains the chemical properties of oxygen is the oxygen molecule O2.

The oxygen atom does not determine matter because it can be combined into different molecules in different numbers. Noble gases are monoatomic molecules, so their properties can be determined by atoms.

Elements can only say that a certain substance is made up of what elements, and there is no distinction between the number of elements.
