Question

1. copper (ii) chloride bond: i formula: agno3

Explanation:

Step1: Determine the bond type

Copper (II) chloride is formed between a metal (copper) and a non - metal (chlorine). Ionic bonds are formed between metals and non - metals.

Step2: Write the correct formula

The copper ion has a charge of \(Cu^{2 +}\) and the chloride ion has a charge of \(Cl^{-}\). Using the criss - cross method (the magnitude of the charge of one ion becomes the subscript of the other ion), the formula is \(CuCl_{2}\).

Answer:

Bond: Ionic; Formula: \(CuCl_{2}\)
