$_{86}A^{222} \to _{84}B^{210}$. In this reaction,how many $\alpha$ and $\beta$ particles are emitted?

$A$ free neutron decays spontaneously into :

What is $\alpha-$,$\beta-$ and $\gamma-$decay? Write their general formulas.

During a $\beta^{-}$-decay,

Beta rays emitted by a radioactive material are

Consider a radioactive nucleus $A$ which decays to a stable nucleus $C$ through the following sequence: $A \to B \to C$. Here $B$ is an intermediate nucleus which is also radioactive. Considering that there are $N_0$ atoms of $A$ initially,plot the graph showing the variation of the number of atoms of $A$ and $B$ versus time.
