β⁻ emission is an emission of an electron by converting a neutron
to a proton. Hence, in β⁻<span> decay, the atomic
number of daughter atom increases by 1 than the parent atom and
mass number is not changed in the formed daughter nucleus.</span>
Hence, formed daughter atom should have 89 + 1 = 90 as atomic number. Hence, the daughter atom should be Th (<span>Thorium)</span>
<span>The equation is</span>
₈₉²²⁸Ac → ₉₀²²⁸Th + ₋₁⁰β + energy<span>
