Question

question 22 1 pts radioactive beta decay of zinc - 72 produces which isotope: copper - 67 gallium - 72 zinc - 71 germanium - 72

Explanation:

In beta - decay, a neutron in the nucleus is converted into a proton and an electron. For zinc - 72 (atomic number 30), when it undergoes beta - decay, the number of protons increases by 1 while the mass number remains the same. The element with atomic number 31 is gallium. So zinc - 72 undergoes beta - decay to form gallium - 72.

Answer:

B. Gallium - 72
