Elements P, Q, R, S have 6, 11, 15, 17 electrons respectively, therefore,


Question

Elements P, Q, R, S have 6, 11, 15, 17 electrons respectively, therefore,

Options

A) P will form an electrovalent bond with R

B) Q will form a covalent bond with S

C) R will form an electrovalent bond with S

D) Q will form an electrovalent bond with S


The correct answer is D.

Explanation:

P 6 = 2, 4
Q 11 = 2, 8, 1
R 15 = 2, 8, 5
S 17 = 2, 8, 7
Given the above is the electronic arrangement of PQRS elements, Q will form an electrovalent bond with S. Without argument, D is the answer because electrovalency involves the transfer of electron. Already, Q is 11 with electronic configuration of 2, 8, 1, i.e. having 1 valence electron which is ready to be lost by the atom of element Q, also, S is 17, with electronic configuration of 2, 8, 7. There the 7 valence electron of S attracts that only 1 electron to attain a stable octet structure.
