Question

A sulphide ion has a positive charge.

• A. True
• B. False

Answer 1

The correct option is B False

Formation of sulphide ion from sulphur atom:

1. The atomic number of Sulphur $\mathbf{\left(}\mathbf{S}\mathbf{\right)}$ is $16$.
2. Thus, the electronic configuration of Sulphur is $(2,8,6)$.
3. From the electronic configuration, the number of valence electrons of Sulphur are $6$.
4. To have eight electrons in the valence shell i.e. to complete an octet, Sulphur atom gains $2$ electrons.
5. As $2$ electrons are gained, Sulphur atom gains two negative charges and becomes a Sulphide anion $\mathbf{\left(}{\mathbf{S}}^{\mathbf{2}\mathbf{-}}\mathbf{\right)}$.
6. The reaction is: $\mathrm{S}+2{\mathrm{e}}^{-}\to {\mathrm{S}}^{2-}$.
7. Thus, Sulphide ion has a negative charge.

Therefore, the given statement is false.
