A nucleus undertgoes `beta`-decay. How does its (i) mass number (ii) atomic number change ?

A nucleus undergoes beta^(-)-decay . How does its mass number

A nucleus undergoes beta^(-)-decay . How does its atomic number change?

When a nucleus undergoes radioactive decay, its new mass number is

If a radioactive element emits - (i) alpha -particle and (ii) beta -particle, then how its mass number and atomic number will change?

Mass number of a nucleus X is A and atomic number is Z. Find mass number and atomic number of the new nucleus (say Y) after the emission of m-alpha particles and n-beta particles.
