The radius of hydrogen atom in the ground state is 0.53 Å, the radius of Li^(2+) in the similar state is

The radius of hydrogen atom in the ground state is 0.53 Å, the radius

1.	The radius of hydrogen atom in the ground state is 0.53 Å, the radius of Li^(2+) in the similar state is
Answer» `1.06 A^@` `0.265 A^@` `0.175 A^@` `0.53 A^@` SOLUTION :`R = (n^2)/(Z) (0.529) A^@ , ` for `LI^(2+) (Z=2) , n=1`
