How does an atom change if all of its electrons are removed? the atom’s volume increases. the atom’s mass increases. the atom becomes positively charged. the atom becomes negatively charged.

The correct answer is C.) The atom becomes positively charged.

If an atom loses or gains an electron, it becomes an ion.

If an electron loses all of it's electrons, then it becomes positively charged because the charge of the protons now outweigh the charge of the electrons.(because there are none.)

Hope this helps!
