A nucleus of beryllium-10 ( 10 4 Be) decays into an isotope of boron by

Question:

A nucleus of beryllium-10 (¹⁰₄ Be) decays into an isotope of boron by β⁻ emission. The chemical symbol for boron is B.
a. Write a nuclear decay equation for the nucleus of beryllium-10.
b. Calculate the energy released in this decay and state its form.
(Mass of ¹⁰₄ Be nucleus = 1.662 38 × 10⁻²⁶ kg; mass of boron isotope = 1.662 19 × 10⁻²⁶ kg; mass of electron = 9.109 56 × 10⁻³¹ kg.)
