Question

Which statement accurately describes the charge of the nucleus of an atom? A. The nucleus can be either positively charged or neutral. B. The nucleus never has an electrical charge. C. The nucleus always has a positive charge. D. The charge of a nucleus can change from positive to negative.

Answer 1

Answer: Option (A) is the correct answer.

Step-by-step explanation:

An atom contains three sub-atomic particles namely protons, neutrons and electrons.

The nucleus of an atom contains protons and neutrons only. Whereas electrons revolve around the nucleus. Protons are positively charged, neutrons have no charge and electrons are negatively charged.

When an atom is neutral then number of protons equal the number of electrons. Hence, the atom becomes neutral as positive charge is equal to negative charge and thus gets cancelled.

Therefore, a nucleus can be either positively charged or neutral.

Answer 2

A. The nucleus can be either positively charged or neutral.

The nucleus is located at the center of an atom wherein it contains the protons and the neutrons.
