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

Elements P, Q, R, S have 6, 11, 15, 17 electrons respectively, therefore,
  • 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
  • E. Q will form a covalent bond with R
Correct Answer: Option 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
