Question

With reference to the formation of compounds from atoms by electron transfer – electron valency, state the basic steps in the conversion of sodium and chlorine atoms to sodium and chloride ions leading to the formation of the compound – sodium chloride.
[electronic configuration of: Na = 2, 8, 1 & Cl = 2, 8, 7]

Answer 1

Electronic configuration

        Na                        Cl
11 = 2, 8, 1           17 = 2, 8, 7

\[\ce{Na+ + Cl-}\]
⇒ NaCl compound
