(b) 10
(c) 9
(d) 8

Answer 1

Answer:

d)8

...... .........

the electrons in a valence electrons in a sulphide ion is 8

Answer 2

Answer:

The number of valence electrons in a sulphide ion $S^{2-}$ is 8

Explanation:

• The the number of valence electrons in a sulphide ion $S^{2-}$  is 8.
• Option D is correct for this question.
• The Sulphur atom has 6 valence electrons, and when it gains 2 more electrons to form $S^{2-}$, then it has 8 valence electrons.
• The Sulphur has 16 electrons and 16 protons. but the ionic atoms electron quantity changes depending on how many it has gained.
• It has gained 2 electrons, which means it has now 18 electrons and 16 protons.

The number of valence electrons in a sulphide ion $S^{2-}$ is 8
