Question

give reason: ions are more stable than atoms.

Answer 1

The ions so arrange themselves that the positive and negative charges alternate and balance one another out

Sodium chloride is a solid food additive that is more stable than either of its constituent parts, all because the outermost energy levels of its atoms are filled with electrons.

Answer 2

to complete their valence shell some atoms lose electrons .... so they became ions and became more stable than their parent atom....
