Question

Knowing what you know about the nucleus and the subatomic particles in the nucleus, what do you think is the charge of the nucleus of an atom?

Answer 1

Explanation:

An atom consists of three subatomic particles which are protons, neutrons and electrons.

Protons and neutrons are placed inside the nucleus whereas electrons revolve around the nucleus.

Protons are positively charged particles and neutrons have no charge. On the other hand, electrons are negatively charged species.

Thus, we can conclude that charge of the nucleus is positive as neutrons have no charge so the charge of protons bring positive charge on nucleus of atom.

Answer 2

The "charge" of a nucleus is a net positive charge due to the positively-charged protons. Because an atom's nucleus only has protons and neutrons, and neutrons have no charge, there is nothing to cancel out the positive charge of the protons.
