Question

Name the particles which are present in the nu­cleus and what type of charge is there on them?

Answer 1

Nucleus:

The central part of an atom which contains protons and neutrons is known as the nucleus.

Sub-atomic particles in the nucleus:

The nucleus contains two types of sub-atomic particles: protons and neutrons.

1. Protons: The protons are positively charged. Protons are denoted as ${\mathrm{p}}^{+}$.
2. Neutrons: The neutrons are electrically neutral. Neutrons are denoted as $\mathrm{n}$.

Thus, the sub-atomic particles present in the nu­cleus are positively charged protons and electrically neutral neutrons.
