There is SULF and then they finish the word with IDE . Most compound names end with IDE . Nitrogen shares its electrons with the Chlorine atoms, so all of the atoms have their shells filled. Take a look at the dots around the atoms. You should know that even though there are two electrons involved in a bond, those electrons are used in different ways.
Ionic bonds happen when electrons are given up by one atom to another.
Covalent bonds happen when electrons are shared by both atoms. Andrew Rader Studios, All rights reserved.
