Which is the correct order of the quantities for the 1st, 2nd and 3rd orbits of the $H e^{+}$ ion :-

Answer:

Solution:

v is proportional to Z/n, so it falls as n rises: (A) is correct.

KE is proportional to $1/ n^{2}$ and falls: (B) is wrong.

$E = - 54.4/ n^{2}$ eV rises with $n (E_{1} < E_{2} < E_{3})$ : (C) is wrong.

r is proportional to $n^{2}$ and rises: (D) is wrong.

Answer: (A).
