Answer 2

Magnesium is an element having the same number of protons, electrons, and neutrons as subatomic particles.

• The protons and electrons are the positively charged and negatively charged particles  (respectively )of an element.
• Neutron is the particles present inside the nucleus of an atom and have no charge.
• The number of protons, electrons, and neutrons of the elements are given below:

• Element: No. of protons- No. of electrons- No. of neutrons

1. Aluminum: 13-13-14
2. Magnesium: 12-12-12
3. Phosphorous: 15-15-16
4. Chlorine: 17-17-18

• Hence, from the above data, we can conclude that magnesium is the right answer.
