Strontium 92 undergoing beta decay. Express your answer as a nuclear equation.

 The nuclear equation for the beta decay is

⁹²₃₈St>⁹²₃₉Y +     ⁰₋₁e

Explanation:

Beta decay(beta-minus and beta-plus.) occurs due to the fact that some atoms are unstable and to become stable must undergo a decay.

The beta decay that occurs in Strontium  is a beta-minus decay,where it changes to another element since its atom gains a proton

A beta decay (beta minus) occurs when an atom emits beta particle (   ⁰₋₁e) Here in Strontium  undergoing a beta(minus) decay, the mass number remains the same but a proton was gained. Hence the new  isotope is  Yttrium ⁹²₃₉Y .

⁹²₃₈St>⁹²₃₉Y +     ⁰₋₁e
