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
Subatomic particles are those particles that are smaller than the atom.
Protons, neutrons, and electrons are the three main subatomic particles present in an atom.
Protons have a positive (+) charge. Proton is represented by P.
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)
