Question

the atomic numbers of 4 elements p,q,r,s are 6,10,12,17 respectively which two elements can combine to form a covalent compound A)P and R B) Q and S C)P and S D)R and S​

Answer 1

Answer:

(C)

Explanation:

covalent compounds are made by shareing electrons

P needs two electron to comlete octate 2-8

2 will used in k remains 4 electron, now it requires 4 electron to complete the shell

S need to share 1 electron to form octet.2in k re,main 15, 8 in l remains 7 so it require 1 to complete shell for M orbit

compounds are made based on octet rule by $s^{2}-p^{6}$
