The most probable simple, stable ion formed by sulfur is?

Question

a) SO4 2- b)S2+ c) S- d) SO3 2- e) S2-

Answer 1

The answer should be (e)
a) SO4 2- sulphate ions can be decomposed by heat to oxide and sulphur trioxide
b)S2+ this ion is not easily formed
c) S- this ion is also not easily formed
d) SO3 2- can be easily reacted upon by acid to give sulphur dioxide gas and water
e) S2- sulphide ion is very stable as it has the inert gas structure when sulphur atoms each gain 2 electrons

Answer 2

Sulfur has atomic number Z = 16, so the electronic configuration of S is:

K: 2, L: 8, M: 6

To complete 8 electrons in its outer shell usually it takes 2 electrons so the most probable simple, stable ion formed by sulfur is:

S2-

Answer 3

S2- would certainly qualify as the simplest and likely most probably given that sulfur exists naturally in the uncombined state. It only needs 2 electrons to achieve the noble gas configuration.

Answer 4

S2-

By gaining two e- the sulfur ion has the same e- configuration as the nearest noble gas.

Answer 5

I'd say SO4 2-. I know H2SO4 is a strong diprotic acid, which means the conjugate bases HSO4 - and SO4 2- must both be fairly stable.

Answer 6

E. Sulfur being a chalcogen will pick up 2 electrons to form sulfide and become isoelectronic with argon.

Sulfate and sulfite are not "simple" ions.
