Elements P, Q, R, S, and \(6,11,15\), and 17 electrons respectively, therefore ____________
A. Q will form a covalent bond with \(S\) B. Q will form an electrovalent bond with \(\mathrm{S}\) C. \(R\) will form an electrovalent bond with \(S\) D. will form a covalent bond with \(R\)
Correct Answer: B
Explanation
From the electronic structure of \(Q\) and \(S(Q=\) \(2,8,1\) and \(\mathrm{S}=2,8,7)\), Q will lose an electron to \(\mathrm{S}\) to form a positive ion while \(\mathrm{S}\) forms a negative ion. Then, the union between \(\mathrm{Q}\) and \(\mathrm{S}\) is ionic/electrovalent bond.
