When sodium and Chlorine reacts then:

AEnergy is releases and ionic bond is formed
Correct Answer
BEnergy id released and a covalent bond is formed
CEnergy is absorbed and ionic bond is formed
DEnergy is absorbed and covalent bond is formed

Solution

When $$\text{sodium and chlorine react, an ionic bond is formed, and formation of ionic bond is fast and exothermic}$$4.Bond formation is always exothermic.
An exothermic reaction ($$ΔH$$ $$negative$$, $$heat$$ $$produced$$) results when the bonds in the products are stronger than the bonds in the reactants.
Option A is a correct answer.
