Question 639: Atoms & Nuclei

Question

In which of the following systems will the radius of the first orbit (n = 1) be minimum ?

Accepted Answer

As Radius of first orbit, r $$ \propto $$ $${1 \over Z}$$
for doubly ionized lithium Z (= 3) will be maximum,
hence for doubly ionized lithium, r will be minimum.

Answer
