Rutherfords experiments , which established the nuclear model of atom , used a beam of:-

A

helium atoms, which impinged on a gold foil and got scattered

B

`beta` particles, which impinged on a gold foil and got scattered

C

helium nuclei, which impinged on a gold foil and got scattered

D

`gamma` rays, which impinged on a gold foil and got scattered

Text Solution

Verified by Experts

The correct Answer is:
C
Projectiles used by Rutherfored were alpha particles which are high enegry, positively charged `He` ions emitted during radioactive decay. An alpha particle has charge `2+` and mass `4u`.
