Question

what is ion ?write its type​

Answer 1

Answer:

An ion is a positively or negatively charged atom (or group of atoms). An ion is formed by the loss or gain of electrons by an atom, so it contains an unequal number of electrons and protons. Example: Sodium ion Na+, magnesium ion Mg2+, chloride ion Cl–, and oxide ion O2–.

Answer 2

Answer:

An ion is a positively or negatively charged atom (or group of atoms). An ion is formed by the loss or gain of electrons by an atom, so it contains an unequal number of electrons and protons. Example: Sodium ion Na+, magnesium ion Mg2+, chloride ion Cl–, and oxide ion O2–.An ion is a positively or negatively charged atom or groups of atoms. There are two types of ions: An atom loses one or more electrons from its valence shell. It becomes positively charged. ... To stabilize the atom, sodium loses one electron and is a deficit of the negative chargeThe two types of ions are cation and anion. Cation: A positively charged particle in a molecule is called cation. Example: Na +, Ca +2. Anion: An anion is a negatively charged particle in a molecule.
