If you want to change the charge of your atom you can either

Add a proton or an electron

Explanation:

If you want to change the charge on an atom, you can either add a proton or an electron.

The charge on an atom is the difference between the number of protons and electrons it carries.

When you add an electron to a neutral atom, it becomes negatively charged because the number of electrons is now more.

When you add an extra proton to a neutral atom, it becomes positively charged because the number of protons is now more. But when you add a proton to an atom, the atom becomes another element.

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
