Question
An isotone of 
is :
is :Options
A.
B.
C.
D.
Solution
Isotones have same nymber of neutrons and thus have same value for (A - Z) for
32Ge76, A - Z = 76 - 32 = 44
(b) 33As77, A - z = 77 - 33 = 44
(d) 34Se78, A - Z = 78 - 38 = 44
32Ge76, A - Z = 76 - 32 = 44
(b) 33As77, A - z = 77 - 33 = 44
(d) 34Se78, A - Z = 78 - 38 = 44
