Explanation / Answer

1) Atom is made up of proton, neutron and electrons.

Protons are positively charged.

Electrons are negatively charged.

Neutrons have neutral charge.

The size is very small and mostly the structure has empty space.

Protons and neutrons are in nucleus and electrons are found in the space surrounding the nucleus.
