Q. Emission of a beta particle by an atom of an element results in the formation of:

ManipalManipal 2003Structure of Atom

Solution:

${ }_{1} H ^{3} \longrightarrow { }_{2} He ^{3}+{ }_{-1} e^{0}$
${ }_{1} H ^{3}$ and ${ }_{2} He ^{3}$ are isobars (having same mass no.)
As, in the emission of $\beta$-particle, mass number does not change. Hence isobars are obtained.
