Question

how is an ionic bond formed

Answer 1

hey dear......!!

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

An Ionic bond is formed between a metal and a non metal through the transfer of electrons.

For example, sodium has 1 valence electron while Chlorine has 7 valence electrons.

So, sodium donates its electron to Chlorine and both complete their respective octets.
