Step-by-step explanation:

Answer 2

1. Alpha particles consist of two protons and two neutrons.

Step-by-step explanation:

Alpha particles are generally produced in the process of alpha decay, a radio active decay in which an atom loses an helium atom.

AN alpha particle is identical to the helium particle. The helium particle has mass number of 4 and atomic number of 2. This means;

Number of protons = 2

Number of neutrons = Mass Number - Atomic Number = 2

The correct option is option 1.
