If the ratio of energies of electron in the excited states of H and Li ²⁺ is 1: 9 , the radius ratio of electron in the same excited states of H and Li ²⁺ is

Step-by-step solution

For same excited state r 1 Z and E Z^2 Where, r= radius of element Z= atomic number of element ' Z ' for ( H ) and ( Li ²⁺ ) are 1 and 3 respectively thus, aligned & r_ ( H ) r_ ( L ²⁺ ) = Z_ ( Li ²⁺ ) Z( H ) & r_ ( H ) r ( Li ²⁺ ) = 3 1 =3: 1 aligned
