Question

The energy of second bohr orbital of the hydrogen atom is_328kj/mol.Hence the energy of fourth bohr orbital should be

Answer 1

Energy = -2.18 × 10 ^-18 × Z​2 / n2 ...

Here z = 1 since it is H atom....

So... E1 / E2 = n22 / n12 ....

Here E1 = -328.....

n​1 = 2..

n​2 = 4....

Now substitue the values to get the ans....

You will definitely get it...
