Answer 1

The following statement is not true is : a positron is the antiparticle of a proton .

The statement that are true is given below :

• beta decay occurs when a neutron changes into a proton while emitting an electron.
• positrons are similar in ionizing power and penetrating power to beta particles .
• an alpha particle is a He²⁺ ion
