Question

Scandium Sulfide. Would i be correct in thinking that the bonding associated with this compound is Ionic. I think this as the two ions involved are oppositely charged?

If im wrong could you please tell me why. Thanks so Much in Advance.

Answer 1

We generally call those compounds with an electronegativity difference of 1.8 or greater ionic. The difference here is about 1.22 which means a polar covalent bond. http://www.chm.davidson.edu/ronutt/che115/electroneg.htm
