Thermal stability of the hydrides decreases gradually from textN textH text3 to textBi textH3. This is due to the reason that atomic size of the element increases down the group and N?H bond strength decreases.

Q. The most stable hydride is

$N H_{3}$

$P H_{3}$

$A s H_{3}$

$S b H_{3}$

Thermal stability of the hydrides decreases gradually from $N H_{3}$ to $Bi H_{3} .$ This is due to the reason that atomic size of the element increases down the group and N?H bond strength decreases.
