which argument best explains the charge of an atomic nucleus

An atom refers to a smallest, indivisible unit that comprises the matter that forms all chemical elements. Therefore, atoms are typically considered as the fundamental building blocks of matter which determines the structure of a chemical element.

Generally, an atom comprises three (3) distinct particles and these are;

• Protons.
  

• Neutrons.
  

• Electrons.
  

Protons refers to the positively charged subatomic particles of a chemical element and an atomic nucleus.

On the other hand, electrons are the negatively charged subatomic particles of a chemical element with a magnitude of -1.

From the above definition, we can deduce that an atomic nucleus which is composed of protons is positively charged.
