Question

What would happen if an electron was added to an atom?

Answer 1

2)

it’s charge would increase by -1

Explanation:

The type of atoms is usually determined by the number of protons. Different isotopes of an atom differ in the number of neutrons only. The number of electrons, however, in neutral atoms is the same as that of the protons. Its charge is zero because the positive charge of the protons cancels out with the negative of the electrons. Adding an electron to a neutral atom, therefore, increases the negative charge of the atom by 1
