Question

Element X has 12 neutrons in its nucleus. To which group in the periodic table would it belong?

• A. 1
• B. 2
• C. 3
• D. cannot be predicted

Answer 1

The correct option is D

cannot be predicted

Explanation for correct answer:

• The element's position in the periodic table cannot be predicted based on the number of neutrons present in the nucleus because the number of neutrons does not indicate the atomic number.
• The atomic number or group in the periodic table can be explained using the number of protons rather than neutrons.
• Neutrons are subatomic particles that are essential components of atomic nuclei. Neutrons have no net electric charge attached to them. They do, however, have mass that is slightly greater in magnitude than that of a proton; the neutron, on the other hand, is neutral. In other words, it has no charge and is thus neither attracted nor repellent to other objects.
• Hence, option d is correct.
