Explanation:
Brass (a copper-zinc alloy)-The brass bond is brittle because it is a metal alloy.
Rubber-Rubber bonding is covalent.
Barium sulfide (BaS) — Bonding is primarily ionic (but some covalent) depending on the respective Ba and S positions in the periodic table.
Solid xenon-Bonding is van der Waals in solid xenon, since xenon is a noble gas.
Bronze-Bonding is metallic in that it is an alloy with silver.
Nylon-The bonding in nylon is primarily covalent with some van der Waals Forces.
Aluminum phosphide (AlP)-Aluminum phosphide (AlP) bonding is covalent in principle but it also has some ionic character.
