Which of the following will form an ionic bond?AK and BrBC and ClCNi and FeDN and O

The formation of an ionic bond involves the transfer of electrons from one atom to another. This typically occurs between a metal and a non-metal.

Here are the steps to determine which pair will form an ionic bond:

1. Identify the type of each element: metal or non-metal.

   A. K (Potassium) is a metal and Br (Bromine) is a non-metal.

   B. C (Carbon) and Cl (Chlorine) are both non-metals.

   C. Ni (Nickel) and Fe (Iron) are both metals.

   D. N (Nitrogen) and O (Oxygen) are both non-metals.

2. As mentioned, ionic bonds typically form between a metal and a non-metal.

Therefore, the pair that will form an ionic bond is K (Potassium) and Br (Bromine).
