The radius of hydrogen atom in the ground state is

0.53{A^0}

. The radius of

L{i^{2 + }}

ion (atomic number =3) in a similar state is

View answer and explanation

Correct option: A

0.176 Å

Option A (0.176 Å) is correct because the radius of

Li^{2+}

is calculated using the formula

{r_n} = \frac{{{r_0} \times {n^2}}}{Z}

.
