Answer 1

Alpha particle...........> decreases the atomic number of an atom

Beta particles .............> increases the atomic number of the atom

Gamma particle ..........> does not change the atomic number of the atom

Step-by-step explanation

The three types of radioactive particles are;

1. Alpha particle

2. Beta particle

3. Gamma particle

Alpha particles has a positive charge with atomic number 2 and mass number 4

Any atom that gives off alpha particle, will have it atomic number drops by 2 and its mass number drops by 4

Hence, alpha particle decreases the atomic number of an atom

Beta particles; The atomic number of a beta particle changes, it can either be positive or negative

When an atom gives off a beta particle, the mass number number of the atom remains unchanged but the atomic number increases

Hence, beta particles increases the atomic number of the atom

Gamma particle is a neutral particle and it does not have any charge on it

When an atom gives off a gamma particle, the mass and atomic numbers of the atom remain unchanged

Hence, gamma particle does not change the atomic number of the atom
