Question

Answer the following questions if the mass number of sulphur atom is 32.
(i) what is the valency of sulphur?
(ii) draw the atomic structure of S-²
(iii) which will be more stable: S- atom or S‐²? give reason
(iv) find the number of neutrons present in sulphur atom.
(v) An element M reacts with sulphur to form MS. what will be the valency M?​

Answer 1

(I) in order to achieve stability, sulfur has to gain 2 electrons. Therefore, the valency of sulphur is 2.

(iii) S‐²

(iv) 16
