Question

Write 3 or 4 point on the following:-
1]Electron
2]Proton
3]Neutron

Answer 1

Hlo...
Here is ur answer :-
1) Electron :-Electron is negatively charged particle and has an absolute charge of 1.602×10^-2
Electron has an absolute mass of 9.11×10^-31
Electrons are located outside the nucleus
2)Proton:- Proton is a positively charged particle and has an absolute charge of 1.602×10^-19.Proton has an absolute mass of 1.672×10^-27kg which is equal to 1 Amu.
Protons are located inside the nucleus.
Neutron:-Neutron is a neutal particle carrying no charge. Neutron is slightly heavier than proton. Protons are also located inside the nucleus.
Hope it will help u

Answer 2

1]Electron
•Electron was discovered by JJ Thomson in 1897.
•Magnitude of charge on electron=1.6 ×10-19 coulomb.
•Mass of electron=9.1×10-28 g or 9.1×10-31 kg.
2]Proton
•The existence of positively charged particles in an atom was shown by E Goldstein in 1886.
•Mass of proton=1.6×10-27 kg.
3]Neutron
•The neutrons were discovered by James Chadwick.
•These particles are neutral having charge 0.
•Their mass is nearly same as that of a hydrogen atom.
