Question

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

Answer 1

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’.
