Alpha rays emitted from a radioactive substance are
- A negatively charged particles
- B doubly ionised helium atoms
- C ionised hydrogen nuclei
- D uncharged particles
Answer & Solution
Correct Answer
(B) doubly ionised helium atoms
Step-by-step Solution
Detailed explanation
\(\alpha\)-rays are a bunch of particles consisting of 2 neutrons and 2 protons. Hence, a \(\alpha\)-particle is a doubly ionised helium-atom.
