A radio-active elements emits one `alpha` and `beta` particles then mass no. of daughter element is :

A radioactive nucleus decays by emitting one alpha and two beta particles, the daughter nucleus is ………………….. of the parent

A radioactive nucleus decays by emitting one alpha and two beta particles, the daughter nucleus is ….. Of the parent.

Due to emission of beta -particle the mass of the daughter element-

A redioactive element ._(Z)X^(A) emits an alpha particle and changes into

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

N atoms of a radioactive element emit n alpha particles per second. The half-life of tge element is.
