can you help me with this

what is the isotope symbol for this Complete and balance each of the following nuclear equations.

Part 1 of 3

83
38Sr11e +
0

83
30

To complete and balance the nuclear equation, you need to identify the missing isotope symbol for the element with atomic number 83.

The element with atomic number 83 is Bismuth (Bi), so the isotope symbol for the element 83Bi is:

^209_83Bi

Therefore, the completed and balanced nuclear equation is:

^209_83Bi -> ^209_84Po + ^0_-1e
