Atoms And Nuclei Question 133

Question: Which state of triply ionised Baryllium $(B e^{+ + +})$ has the same orbital radius as that of the ground state of hydrogen [KCET 2004]

Options:

A) n = 4

B) n = 3

C) n = 2

D) n = 1

Show Answer

Answer:

Correct Answer: C

Solution:

Radius of nth orbit for any hydrogen like atom $r_{n} = r_{0} (\frac{n^{2}}{Z})$ ( $r_{0} =$ radius of first orbit of $H_{2}$ -atom) If $r_{n} = r_{0}$
Þ $n = \sqrt{Z} .$ For Be+++, Z = 4 Þ n = 2.
