The radius of fifth orbit of Li + + is _______ × 10 - 12 m . Take: radius of hydrogen atom = 0 . 51 A ∘

Correct answer

0

Step-by-step solution

The formula to calculate the radius of Lithium-ion is given by R Li = R H × n 2 Z       . . . ( 1 ) Substitute the values of the known parameters into equation (1) to calculate the required radius of the ion. R L i = 0 . 51 × 25 3 × 10 - 10   m = 425 × 10 - 12   m
