1. Compare the properties of electrons, protons and neutrons​

Answer»

ELECTRONS:

  • Electrons are negatively charged component.
  • The MASS of electron = \dfrac{1}{2000} × mass of hydrogen atom.
  • Electrons are present in outer shell of the atoms.
  • An electron is represented as ‘e’.

PROTON:

  • Protons are positively charged component.
  • The mass of proton = The mass of neutron.
  • Protons are present in the NUCLEUS of an atom.
  • A proton is represented by ‘P’.

Neutron:

  • Neutrons are neutral.
  • The mass of neutron = The mass of proton.
  • Neutrons are present in nucleus of all atoms (except hydrogen).
  • A neutron is represented as ‘n’.
