Question

Which nucleus completes the following equation?

Please ignore the answer I chose, it might be wrong

Answer 1

D.
`^(39)_(18) Ar`

Step-by-step explanation:

The given nuclear equation is the beta decay of chorine in which an electron, known as a beta particle, is given off from within the nucleus due to the breakdown of a neutron within the nucleus into a proton and a beta particle, such that the atomic number is increased by 1 from 17 to 18, which is the atomic number or argon, Ar, as follows;

`^(39)_(17)Cl \ \rightarrow \ ^0_(-1) e + \ ^(39)_(18) Ar`
