The main reaction during electrovalent bond formation is

Which pair of atoms forms the strongest ionic bond?

Describe the steps involved in the formation of an ionic bond and the associated energy changes.

Write Lewis symbols for the following atoms and ions:
$S$ and $S^{2-}$; $Al$ and $Al^{3+}$; $H$ and $H^{-}$

Given below are two statements:
Assertion $(A)$: Ionic compounds are formed by non-directional bonds.
Reasoning $(R)$: They are soluble in nonpolar solvents.
The correct answer is:

What is an electrovalent (ionic) bond? Explain with any two examples.
