Question

16. Explain the octet rule for formation of -
a] Sodium chloride from a sodium atom and a chlorine atom.
b] Nitrogen molecule from two nitrogen atoms.​

Answer 1

Explanation:

Octet rule is every element react to complete its octet .

Na . has atomic no. = 11

electronic configuration = 2,8 , 1

to complete its octet Na want

to donate it's

1 valence electron .

Cl has atomic no.= 17

electronic configuration = 2, 8, 7.

to complete its octet Cl has to gain 1 electron

when Na and Cl react sodium donate its 1 electron and chlorine take it

this way octet of both elements is complete
