Question

what is the ion formed from sulfur? s⁻² s⁺⁶ s⁻⁶ s⁺²

Explanation:

Step1: Recall sulfur's valence electrons

Sulfur has 6 valence electrons. It wants to gain 2 electrons to achieve a stable octet configuration.

Step2: Determine the ion formed

When it gains 2 electrons, it forms an anion with a - 2 charge. So the ion is $S^{-2}$.

Answer:

$S^{-2}$
