Question

Explain the things given in the chart​

Answer 1

Your answer :-

Ions, nuclei and subatomic particles have extremely small charges such as the proton (1.6x10-19Coulombs) so instead of stating the charge in Coulombs it is compared to the charge of a proton.

The charge on an ion is shown at the top right of the element symbol
