Sulfur forms a -2 ion in an attempt to achieve a complete electron shell that is isoelectronic with Argon. In order to achieve a full 3p shell, Sulfur must gain 2 electrons, becoming a -2 ion.
A sulfur atom becomes a sulfur ion by losing or gaining electrons. If a sulfur atom loses electrons, it becomes a positively charged sulfur ion (sulfur cation). If it gains electrons, it becomes a negatively charged sulfur ion (sulfur anion).
It becomes a negative ion.
A sulfur atom gains 2 electrons when it becomes a sulfide ion.
It becomes a negative ion.
