Answer 1

The compounds in the question consist of elements that are either metals or non-metals. Covalent bonding occurs between the non-metal elements, while ionic bonding occurs between the metal and non-metal elements.

Step-by-step explanation:

The compounds and their corresponding elements are:

• NO₂: Non-metal (N) and non-metal (O)
• NaCl: Metal (Na) and non-metal (Cl)
• SO₂: Non-metal (S) and non-metal (O)
• N₂: Non-metal (N) and non-metal (N)
• MgBr₂: Metal (Mg) and non-metal (Br)
• CaO: Metal (Ca) and non-metal (O)
• H₂O: Non-metal (H) and non-metal (O)
• K₂O: Metal (K) and non-metal (O)
• Cu-Zn alloy: Metal (Cu) and metal (Zn)
• 0₂: Non-metal (O) and non-metal (O)
• CuCl: Metal (Cu) and non-metal (Cl)
• TiO₂: Metal (Ti) and non-metal (O)
• HF: Non-metal (H) and non-metal (F)
• Rb₂S: Metal (Rb) and non-metal (S)
• Au-Ag mixture: Metal (Au) and metal (Ag)
• Fe₂O₂: Metal (Fe) and non-metal (O)

In general, covalent bonding occurs between non-metal and non-metal elements, whereas ionic bonding occurs between metal and non-metal elements.
