Electrons and ions are completely different concepts.

Electron: one of the basic particles that make up an atom. It has a very small mass and carries a unit negative charge. The number of electrons possessed by different atoms Different, for example, each carbon atom contains 6 electrons, and each oxygen atom contains 8 electrons. Those with higher energy are farther from the nucleus, while those with lower energy are closer to the nucleus. The movement of electrons in regions with different distances from the nucleus is usually called the hierarchical arrangement of electrons.

The mass of the electron: 9.10938215 (45) × 10 kilograms.

Ion: refers to an atom that loses or gains one or several electrons due to the action of itself or the outside world, so that the number of electrons in the outermost shell is 8 or 2 (helium atoms) or no electrons (four neutron) stable structure. This process is called ionization. The energy required or released by the ionization process is called ionization energy.

Differences: 1. Ions can carry 2, 3 or more positive and negative charges; while electrons can only carry one negative charge.

2. Ions originate from atoms and are The existence form of atoms that partially lose or gain electrons can contain one or many electrons; an electron is just an electron, does not have a nuclear structure, and does not have the characteristics of an atomic element.

3. An ion is a certain element, and an electron Just basic particles (components of atoms, just parts)

4. Ions are divided into anions and cations, with positive and negative charges. They can neutralize the electricity and exist in solutions or solids; electrons have only one electricity. , cannot neutralize its own electricity, and must interact with positively charged particles to exist.

The essential difference is that (1) ions are a form of atoms, and electrons are only components of atoms.

The essential difference is that (1) ions are a form of atoms, and electrons are only components of atoms.

(2) Ions may contain electrons, but electrons cannot contain ions.

Relationship: Ions are products formed after atoms or groups of atoms lose or gain electrons,

Electrons are the building blocks of atoms
