Answer 2

Alpha particle

Alpha particle is a positively charged particle having 2 units of positive charge and 4 units of mass.

It is actually helium ion, He2+.

Rutherford’s alpha particles scattering experiment led to the discovery of small positively charged nucleus in the atom which contained protons and neutrons.

When fast moving alpha particles are allowed to strike a thin gold foil of about thousand atoms thick in vacuum, it is found that:-

Most of the fast moving alpha particles passed straight through gold foil.

Some of the alpha particles were deflected by small angles.

About 1 out of every 12000 particles appeared to rebound.
