Sub atomic particles are electrons (e) protons (P) and neutrons (N).

Electrons are negatively charged and it revolves around the nucleus with mass = 9.109381 × 10-31 kilograms.

Protons are positively charged with mass = 1.672621×10-27 kg.

Neutrons have no charge with mass = 1.675 × 10-27 kg.

Both proton and neutron constitute the nucleus of an atom.

Nucleus constitute mass of the atom.

Mass of atom (Z) = P + N

In a neutral atom number of electrons = number of protons.

Number of protons constitute the atomic number of an atom.

For example in carbon

Atomic number = 6

Number of electrons = 6

Number of protons = 6

Atomic mass = 12

Number of neutrons = Z - P = 12 - 6 = 6

  1. Subatomic particles are those particles that are smaller than the atom.

  2. Protons, neutrons, and electrons are the three main subatomic particles present in an atom.

  3. Protons have a positive (+) charge. Proton is represented by P.

  4. Neutrons have no electrical charge. It is represented by L.

  • yes . subatomic particles which are smaller than atoms are electrons(-vecharge) 
  • protons(+ve charge)
  • neutrons(no charge)
