Answer 1

Answer:

d) a compound R2P

Explanation:

Element P needs 2 electrons to complete its octet (valency 2).

whereas element R have a tendency to donate 1 electron to have a stable configuration(valency 1)

so to make a compound, 2 atoms of R and 1 atom of P will be required.

Answer 2

Valency of R = 8-6 = 2

Valency of P = 1

Therefore,

Compound formed = RP2

Thus the option C is correct .
