Question
What type(s) of bonding would be expected for each of the following materials: (match with the correct definition)
A.
The bonding is metallic since it is a metal alloy
B.
Predominantly ionic (but with some covalent character)
C.
The bonding is covalent with perhaps some van der Waals.
D. Predominantly covalent (but with some ionic character)
Brass or bronze: A, B, C, or D?
Rubber or nylon: A, B, C, or D?
BaS: A, B, C, D?
AIP: A,B,C, or D?

Brass or bronze: A, B, C, or D?
Rubber or nylon: A, B, C, or D?
BaS: A, B, C, D?
AIP: A,B,C, or D?
Explanation / Answer
Brass or bronze: A, - This is an alloy so primarily metal bonding
Rubber or nylon: C, This is polymer bound by covalent bonds with some overlaps and so van der Waals
BaS: B, - This is a primarily ionic compound as the difference in electronegativity is 2.58 - 0.89 = 1.69 but it has some covalent character
AIP: D : This is primarily covalent as the difference in electronegativity is 2.19 - 1.61 = 0.58 so it has little ionic character
