Say for D 4 Atomic No = Z Mass Number = A A =182-4-4=174 Z =74-2+1-2=71

Q. In the following nuclear rection,
$D α D_{1} β^{-} D_{2} α D_{3} γ D_{4}$
Mass number of D is $182$ and atomic number is $74.$
Mass number and atomic number of $D_{4}$ respectively will be

174 and 71

174 and 69

172 and 69

172 and 71

Say for $D_{4}$ Atomic $N o = Z$
Mass Number $=$ A
$A = 182 - 4 - 4 = 174$
$Z = 74 - 2 + 1 - 2 = 71$
