Question

how does an atom change if all of its electrons are removed?
○ the atoms volume increases.
○ the atoms mass increases.
○ the atom becomes positively charged.
○ the atom becomes negatively charged.

Explanation:

An atom consists of protons (positive charge), neutrons (neutral), and electrons (negative charge). Electrons have negligible mass compared to protons and neutrons. Removing all electrons:

• Volume: Electrons occupy the electron cloud; removing them would decrease volume, so "volume increases" is wrong.
• Mass: Electrons’ mass is tiny, so removing them barely changes mass, so "mass increases" is wrong.
• Charge: Protons are positive, electrons negative. If all electrons (negative charges) are removed, the atom has more protons than electrons, so it becomes positively charged. "Negatively charged" is wrong as electrons (negative) are removed, not added.

Answer:

The atom becomes positively charged.
