A) isotones
B) isobars
C) isotopes
D) isoelectronics
Correct Answer: C
Solution :
Let atomic mass and atomic number of Y are a and b respectively. Hence, \[{}_{b}{{Y}^{a}}\xrightarrow{-\alpha }{}_{b-2}{{M}^{a-4}}\xrightarrow{-\beta }{}_{b-1}{{N}^{a-4}}\xrightarrow{-\beta }{}_{b}{{X}^{a-4}}\] Hence, X and Y are isotopes (i.e., having equal atomic number but differing in mass number)You need to login to perform this action.
