When K+ and I- combine, a(n) _________ bond results.

Sagot :

An ionic bond. This is because ionic bonds occur between oppositely charged ions.

Answer: Ionic Bond

Explanation:

An ionic bond exists between two dissimilar ions. Cation is positively charged and anion is negatively charged.

Cation lacks electrons i.e. an atom which has more number or protons than electrons forms a cation.

Anion has excess of electrons i.e.when an atom has more electrons than protons.

A charged specie is unstable. It tends to lose or gain electron in order to get neutral and become stable. An ionic bond is formed due to transfer of electron from anion to cation. K⁺ is positively charged -it is a cation. It lacks one electron. I- has one extra electron - it is anion. when K⁺ and I⁻ bond, I⁻ loses its electron to K⁺ and ionic bond is created.

K⁺ + I⁻ → KI
