Question

select the statement that accurately explains why an atom is left with a positive charge when it loses electrons.
there are more positively charged subatomic particles in the atoms nucleus.
the atom gains another neutrally charged subatomic particle when it loses an electron.
there are a greater number of electron particles in the atoms nucleus.
the atom gains another positively charged subatomic particle when it loses an electron.

Explanation:

An atom has protons (positively charged), neutrons (neutral), and electrons (negatively charged). In a neutral atom, the number of protons equals the number of electrons. When an atom loses electrons, the number of protons (positively - charged subatomic particles) in the nucleus is greater than the number of electrons. So, the atom has a net positive charge.

• The first option: If there are more positively charged subatomic particles (protons) in the nucleus compared to the number of electrons (after electron loss), this explains the positive charge.
• The second option: Gaining a neutrally - charged subatomic particle (neutron) when losing an electron does not explain the positive charge. A neutron has no charge, so it won't contribute to a positive charge.
• The third option: Electrons are not in the nucleus. Protons and neutrons are in the nucleus.
• The fourth option: Gaining a positively - charged subatomic particle (proton) when losing an electron is not a common occurrence in simple electron - loss scenarios. Usually, the number of protons in the nucleus remains the same in chemical reactions (involving electron transfer), and it's the change in the number of electrons that causes the charge imbalance.

Answer:

There are more positively charged subatomic particles in the atom’s nucleus.
