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.

Option (c) is the correct answer.

Explanation:

When an atom loses an electron then it acquires a positive charge.

For example, a neutral sodium atom on losing one electron will change into .

On the other hand, when an atom gains an electron then it acquires a negative charge.

For example, a neutral chlorine atom on gaining one electron will change into ion.

Thus, we can conclude that when all of an atom's electrons are removed then the atom becomes positively charged.
