# What is the nuclear equation for Bismuth-214 which undergoes beta decay?

##### 1 Answer

#### Explanation:

The bismuth isotope in question has a mass of

If the mass number is kept the same and the atomic number increases by one,

The electron is released in order to conserve charge.

You can check this is correct by adding together the numbers on the top and bottom of the equation and making sure they are the same on both sides, so that everything possible is conserved.
