Question 48

Deduce which nucleus is formed when potassium-40 absorbs an electron.

Use the nuclear equation below and the list of proton (atomic) numbers to help you:

Argon (Ar): proton number = 18
Potassium (K): proton number = 19
Calcium (Ca): proton number = 20

{}^1_1\text{p} + {}^0_{-1}\text{e} \longrightarrow {}^1_0\text{n}
