# The ratio of the energy of the electron in the ground state of hydrogen to the electron in the first excited state of  is  Option 1) 1:4 Option 2) 1:8 Option 3) 1:16 Option 4) 16:1

As learnt in

Total energy of elctron in nth orbit -

Where z is atomic number

-

We know that total energy of electron in nth orbit,

E1 (ground state of hydrogen) =

E2 (first excited state of Be 3+) =

(n = 2, z = 4)

= -13.6 x 4 eV

Option 2)

1:8

This option is incorrect

Option 3)

1:16

This option is incorrect

Option 4)

16:1

This option is incorrect
