Question

How are ionic substances formed?

Answer 1

An ionic compound is formed by the complete transfer of electrons from a metal to a nonmetal and the resulting ions have achieved an octet. The protons do not change.

Step-by-step explanation:

Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.

Answer 2

Ionic bonds are made when one of the two atoms that are reacting has excess electrons and transfer the electrons to the atom that is deficient in electrons.
