Which numbers are shown in the symbol for a radioactive nuclide?

atomic and mass number

Explanation:

Radioactive decay process is a type of process in which a less stable nuclei decomposes to a stable nuclei by releasing some radiations or particles like alpha, beta particles or gamma-radiations. The radioactive decay follows first order kinetics.

General representation of a radioactive nuclide is given as:  

where,

Z represents Atomic number

A represents Mass number

X represents the symbol of an element

Thus atomic and mass numbers are shown in the symbol for a radioactive nuclide.

i believe the answer is c. "baking" is the gerund, while "baking blueberry muffins" would be the gerund phrase. hope this ! : )
