Question

what type(s) of bonding would be expected for brass (a copper - zinc alloy)?
ionic bonding
van der waals bonding
covalent bonding with some van der waals bonding
metallic bonding

Explanation:

Brass is a metal - metal alloy. Metallic bonding occurs in metals and alloys. In brass (a copper - zinc alloy), the atoms are held together by metallic bonds where the valence electrons are delocalized and form a "sea" of electrons that hold the positively charged metal ions in place.

Answer:

Metallic bonding
