Alpha `(alpha)` particles are

A

`He` atoms

B

`He^(2+)`ions

C

`He^(+)`ions

D

`He^(-)`ions

Text Solution

Verified by Experts

The correct Answer is:
B
Alpha particles are `He^(2+)` ions, i.e. `He`atoms without their two electrons. It was confirmed by the fact that alpha particles yielded `He` gas when they combined with two electrons.
