Question

part b
what type of bonding occurs in the compound from part a?

nuclear

ionic

covalent

metallic

Explanation:

To answer this, we need to recall the types of bonding:

• Nuclear bonding is about atomic nuclei (not for compounds).
• Ionic bonding forms between metals and non - metals (electron transfer).
• Covalent bonding forms between non - metals (electron sharing).
• Metallic bonding is in metals (metal atoms).

Since the question refers to a compound (from Part A, likely a non - metal - non - metal or metal - non - metal compound, but covalent is between non - metals). Assuming the compound from Part A is made of non - metals (e.g., $H_2O$, $CO_2$), covalent bonding occurs via electron sharing between non - metal atoms. Nuclear bonding is irrelevant for compound structure, ionic is metal - non - metal, metallic is for metals. So the correct type is covalent.

Answer:

C. covalent
