Question 28
Easy

The nucleus of the isotope potassium-40 can occasionally capture an inner-orbit electron.

When this occurs, a proton in the nucleus is converted into a neutron, as represented by the equation:

11p+−10e⟶01n {}^1_1\text{p} + {}^{0}_{-1}\text{e} \longrightarrow {}^1_0\text{n} 11​p+−10​e⟶01​n

Describe how capturing an electron affects both the proton number and the mass (nucleon) number of the nucleus.
