Hi, how can I express this problem as a nuclear equation?

Question

A radioisotope emits a positron to form germanium-74.

Answer 1

A positron is like an electron (essentially no mass) but with a positive charge, represented as ⁰₁e

⁷⁴₃₃ X ==> ⁷⁴₃₂Ge + ⁰₁e

Therefore X = As

So, the nuclear equation would be ⁷⁴₃₃As ==> ⁷⁴₃₂Ge + ⁰₁e
