In which of the following systems will the radius of the first orbit (n=1) be minimum?
Options
(a) Single ionised helium
(b) Deutron atom
(c) Hydrogen atom
(d) Doubly ionised lithium
Correct Answer:
Doubly ionised lithium
Explanation:
r ∝ 1 / Z. For doubly ionised lithium, Z = 3
.·. r will be minimum.
