Question

What are neutrons and protons ?

Answer 1

Neutrons are particles that are in the atom that have no charge at all that surround the nucleus. Protons are also particles that surround the nucleus but these ones have a positive charge.

Hope this helps:)

Answer 2

Neutrons and protons are little sub-atomic particles in the nucleus of an atom. They contribute to nearly all of an atom's mass, and are locating in the middle of each atom. Neutrons and protons have similar masses when compared to each other. Neutrons are neutral (have no charge), and a proton has a charge which is roughly equal to +1.6 x 10^-19 Coulombs. This charge is negated by the presence of electrons
