A) 1 : 1
B) 1 : 2
C) 2 : 1
D) 1 : 3
Correct Answer: A
Solution :
For an atom with atomic number A, the radius R of orbit is given by \[R={{R}_{o}}{{A}^{1/3}}\] Since, deuterium is an isotope of hydrogen both having the same atomic number, hence \[\frac{{{R}_{H}}}{{{R}_{D}}}=\frac{1}{1}\]You need to login to perform this action.
