The atomic number of an element is $32$ and mass number $55$ . Calculate the number of neutrons?
$23$
$32$
$25$
$21$

Atomic number or number of protons $= 32$
Mass number $= 55$
Mass number $(A) = N u m b e r o f p r o t o n s + N u m b e r o f n e u t r o n s$
$55 = 32 + N u m b e r o f n e u t r o n s$
Number of neutrons $= 55 - 32$
Number of neutrons $= 23$
