Consider the following radioactive decay process
${ }_{84}^{218} A \stackrel{\alpha}{\longrightarrow} A_1 \stackrel{\beta^{-}}{\longrightarrow} A_2 \stackrel{\gamma}{\longrightarrow} A_3 \stackrel{\alpha}{\longrightarrow} A_4 \stackrel{B^{+}}{\longrightarrow} A_5 \stackrel{\gamma}{\longrightarrow} A_6$
The mass number and the atomic number $A _6$ are given by
$210$ and $82$
$210$ and $84$
$210$ and $80$
$211$ and $80$
What is gamma decay ? Explain by proper example.
Assertion : Radioactive nuclei emit ${\beta ^ - }$ particles.
Reason : Electrons exist inside the nucleus
A certain stable nucleide, after absorbing a neutron, emits $\beta$-particle and the new nucleide splits spontaneously into two $\alpha$-particles. The nucleide is
What is $\alpha -$ , $\beta -$ and $\gamma -$decay ? Write its general formula.
After one $\alpha $ and two $\beta $ emissions
