Question

Identify the particle represented by each symbol as an alpha particle, a beta particle, a gamma ray, a positron, a neutron, or a proton.

a. 11P
b. 42He
c. +10e

Answer 1

`_1^(1) {P}` is symbol for proton emission in the nucleus.

`_2^(4) {He}` symbolises alpha emission, equivalent to helium atom emission of a radioactive particle

`+_1^(0) {e}` is the radiation symbol for positiron particle. which occurs when beta + radioactive decay occurs
