Atoms of different materials have-
number of electrons, protons and neutrons.
The value of the charge on one electron is​

Answer 1

Explanation:

The number of electrons and protons are always equal in all atoms.

This maintains the electrical neutrality of the atom as the positive charges are balanced with negative charges.

If the number of electrons and protons are not equal, then the atom will have a net positive or negative charge and it will form a cation or an anion.
