The Radius Of Hydrogen Atom In The Ground State Is Chemistry Question

The radius of hydrogen atom in the ground state is 0.53 Å. The radius of Li2+ ion (atomic number = 3) in a similar state is

Options

(a) 0.17 Å
(b) 0.265 Å
(c) 0.53 Å
(d) 1.06 Å

Correct Answer:

0.17 Å

Explanation:

State of hydrogen atom (n) = 1(due to ground state). Radius of hydrogen atom (r) = 0.53 Å. Atomic number of Li (Z) = 3. Radius of Li2+ ion = r x n²/Z = 0.53 x 1²/3 = 0.17
