Question

Directions: Compute the charge of the following ions. Show your solutions.

a. Anion with a charge of -3

b. Cation with a charge of +2

c. Anion with a charge of +5

Answer 1

$\text{ a. }\space Q=-3e=-3·(1.602·10^{-19})=-4.81·10^{-19}\text{ C}.\\ \text{ b. }\space Q=2e=-2·(1.602·10^{-19})=-3.20·10^{-19}\text{ C}.\\ \text{ c. }\space Q=5e=-3·(1.602·10^{-19})=8.01·10^{-19}\text{ C}.$
