(a) Sulphur (atomic No. 16)
(b) Chlorine(atomic No. 17)

Answer 1

electronic configuration of

S = 2,8,6

Cl = 2,8,7

here S needs 2 electrons for complete it's octet and Cl needs one electrons to complete it's octet

Answer 2

Answer:

Sulphur forms S²⁻.

Chlorine forms Cl⁻.

Explanation:

Electronic configuration of sulphur is [Ne] 3s² 3p⁴  and configuration of chlorine is [Ne] 3s² 3p⁵. Since sulphur needs two electron to complete its octet and chlorine needs one electron to complete its octet they form S²⁻ and Cl⁻ respectively.
