When forming an ionic compound with one atom of sulfur, two potassium atoms are used. Each potassium atom donates its outermost electron to the sulfur atom, forming ions with a 1+ charge, due to the loss of an electron. When sulfur receives these two electrons, it is ionised itself, becoming an ion with a 2- charge.
When sulfur forms an ion what is its charge?
Think of the octet rule. Therefore a sulfur atom will gain two electrons to form the sulfide anion with a charge of 2− , with the symbol S2− .
When sulfur forms an ion It is referred to as?
However, when non-metallic elements gain electrons to form anions, the end of their name is changed to “-ide.” For example, a fluorine atom gains one electron to become a fluoride ion (F-), and sulfur gains two electrons to become a sulfide ion (S2-).
