The chemical name for K2S.

What is a potassium sulfide. 

200
Electrons found on the outermost orbital of an atom.
What are valence electrons?
300
A group of elements with a full outer ring of electrons making them very stable and highly UNreactive.
What are the noble gases?
300
An atom that has gained or lost one or more electrons as a means to fill its outer shell and therefore has either a negative or positive charge.
