Given a large number of atoms of Cs and S, what compunds would you expect to be able to make?
a)CsS, b)Cs2S, c)CsS2, d)CsS3, e)all the above
How many and what kinds of bonds do you expect to find in the compound CaCO3?
a) Three covalent single bonds, b) Three covalent single bonds, 1 ionic bond, c) 2 covalent single bonds, 1 covalent double bond, 2 ionic bonds, d) 3 covalent single bonds, 2 ionic bonds, e) 2 covalent single bonds, 1 covalent double bond, 1 ionic bond
1) Answer is "b"
Cs has valency 1 and sulpher forms sulphide ions S-2, therefore they can form Cesium sulphide i.e Cs2S
2) Answer is "e"
