Q.1. Compare the properties of electrons, protons and
rties of electrons. protons and neutrons.
protons and neutrons can be compared as below:
Charge : Electron is negatively charged and has an abso
on is negatively charged and has an absolute charge of 1.602 * 1
whereas proton is positively charged and has an absolute charge
hand, neutron is a neutral particle carrying no charge.
vely charged and has an absolute charge of 1.602 x 10-19 coulomb
Mass: Electron has an absolute mass of 9-11 x 10-3kg which is equal
has an absolute mass of 1-672 x 10-27ko which is equal to 1 amu. On the other hand, neutron
mass of 1.675 x 10-27kg, i.e, neutron is slightly heavier than proton.
(iii) Location: Electrons are located outside the nucleus while protons and neutrons a
the nucleus
(iv) Symbol : Electron is represented as _ye ore, proton is represented as ip' or p
represented as on or n.​
