Questions about molecules, atoms, ions...

A molecule is made up of two or more atoms or ions and is the smallest particle that retains the chemical properties of a substance.

Atoms are inseparable in chemical changes, and if they are to be disassembled, they are composed of nuclei and electrons.

Ions are charged (there are positively charged and negatively charged, they can cancel each other out), and atoms and molecules are not charged.

Saying that atoms are not the smallest particles in chemical change "may be because some molecules have no atoms and are made up of ions."

The difference you are talking about is that the individual ones are ionized, the molecules that are composed of two or more people who are not charged (this is not the individual that makes up the molecule, but the whole is not electrified), and the individual atoms that are not electrified.

The smallest particles that maintain the chemical properties of a substance are called molecules.

Molecules are made up of atoms. Air is made up of various molecules.

Atoms refer to the basic particles of chemical reactions, and atoms are inseparable in chemical reactions.

In chemical change, atoms gain or lose electrons and become charged particles, which are called ions.

Ions are electrified, atoms are not charged, and molecules are made up of atoms.

Atoms are inseparable in chemical change and are the smallest particles in chemical change.

It can't be divided anymore ... Molecules are made up of atoms.

The ions are different from the above 2. He is only a form of material composition.

First of all, when an atom loses or gains electrons, it is called an ion, that is, an atom with an electric charge is an ion. Secondly, carbon dioxide is a covalent compound, and there is no disadvantage in it, so it is said to be composed of carbon atoms and oxygen atoms. For ionic compounds, they are composed of an ion and an ion.

Ions: In chemical changes, electrically neutral atoms often gain or lose electrons and become charged particles, which are called ions.

Atom: refers to the basic particles that are inseparable from a chemical reaction, and the atoms are inseparable in a chemical reaction. But in the physical state it can be divided. An atom is made up of a nucleus and an electronic group that moves around the nucleus.

Molecules are made up of atoms, ionic charged atoms are not charged, atoms gain electrons become anions, atoms gain electrons become anions, anions lose electrons become atoms, cations gain electrons become atoms.

Molecule: The smallest particle of a chemical reaction, made up of atoms, many monoatomic molecules, atoms = molecules, such as noble gases, metals, etc.

Atom: The smallest particle that makes up a substance, neutral, a single atom or multiple atoms make up a molecule, and a plurality of molecules then forms a substance, and the atom does not change in the chemical reaction.

Ion: An atom or cluster of atoms that has an electric charge.

Difference Between Molecule and Atom: Can It Be Redivided in Chemical Change. (In chemical change, molecules can be separated, but atoms cannot be separated.) ）

Molecule-to-atom connection: Molecules are made up of atoms.

Difference Between Atom and Ion: Ionic Charged Atom is not charged.

The connection between atoms and ions: atoms gain electrons to become anions, atoms gain electrons to become anions, anions lose electrons to become atoms, cations gain electrons to become atoms.

Substances directly composed of atoms: elemental metals, noble gases. Some non-metallic elements, such as C, S, etc.

Substances directly composed of molecules: some non-metallic elements (such as hydrogen, oxygen, etc.), covalent compounds (such as acids, non-metal oxides, organic compounds, etc.).

Substances directly composed of ions: ionic compounds (e.g., active metal oxides, bases, salts, etc.).

Atom The smallest particle in a chemical change.

Molecule The smallest particle (a substance made up of molecules) that maintains the chemical properties of a substance

Ions are charged atoms or clusters of atoms.

Molecules are made up of atoms, and each atom has a different atomic structure, and when it reaches a stable structure, it loses electrons or gains electrons to form ions.
