This is how you find out.
There are 2 numbers for each atom, top mass number and a bottom atomic number.
Beta particles affect the bottom number only while alpha particles affect both.
Since a beta particle was released, the mass number therefore is still the same, so the answers is polonium-214

Bismuth has 83=Z protons and a number of mass 214
when desintegrating you write
Bi (214 , 83) ---> e (0, -1) + X (214, 84)
and in the periodic table you see that element with Z=84 is polonium
So, you have Polonium 214

The atomic number increases by one during beta emission.
Polonium-214
