In relation to the original atom, the atom that results from beta decay has an atomic number that is

Select one:

a. 2 less

b. the same

c. 1 more

d. 1 less

The atom that results from beta decay has an atomic number 1 more than the original one.

Option c

Explanation:

Beta decay is the process of radioactive disintegration by which unstable atomic nuclei dissipate excess energy and undergo a change of unit of positive charge without changing its mass number.

For eg: The β-decay of Hydrogen-2 which has the atomic number of 1 and mass number of 2 decays to helium-2 having an atomic number of 2 and mass number of 2.
