Question
The charge of an electron is 1.6 × 10–19 coulombs. What will be the value of charge on Na+ ion ?
Solution
The charge on a Na+ ion is also 1.6 × 10–19 coulombs. This is because the Na+ ion has lost one electron, and the charge of an electron is 1.6 × 10–19 coulombs. Therefore, the charge on the Na+ ion is the same as the charge of one electron, but it is positive instead of negative.
