86 A222 longrightarrow 84 B210 Decrease in mass number =222-210 =12 ∴ Number of α-particles emitted =(12/4)=3 86 A222 longrightarrow 80 X210 longrightarrow 84 B 210 Increase in atomic number =84-80=4 ∴ Number of β-particles emitted =4

Q. In the reaction given below $_{86} A^{222} ⟶_{84} B^{210}$ and $β$ -particles are emitted ?

$6 α, 3 β$

$3 α, 4 β$

$4 α, 3 β$

$3 α, 6 β$

$_{86} A^{222} ⟶_{84} B^{210}$
Decrease in mass number $= 222 - 210$
$= 12$
$∴$ Number of $α$ -particles emitted
$= \frac{12}{4} = 3$
$_{86} A^{222} ⟶_{80} X^{210} ⟶_{84} B^{210}$
Increase in atomic number $= 84 - 80 = 4$
$∴$ Number of $β$ -particles emitted $= 4$
