Question

E. What is the difference between an alpha -particle and helium atom ?​

Answer 1

Answer:

An alpha particle is identical to a helium atom that has been stripped of its two electrons; thus, an alpha particle contains two protons and two neutrons. Because an alpha particle has no electrons to balance the positive charge of the two protons, it has a charge of +2 and can be represented as He2+.

Answer 2

Answer:

Alpha particles are nothing but He+2 ions

Alpha particles were used for the discovery of the nucleus of an atom by Rutherford .
