Question

The energy of second bohr orbit of the hydrogen atom is-328kj/mol ;hence the energy of fourth bohr orbit would be

Answer 1

Answer:

-82 kj/mol.

Explanation:

From the question we get to know that the energy of second Bohr orbit of the hydrogen atom is given as -328 kj/mol.

We also know from the atomic structure that the energy of the hydrogen atom is found to be inversely proportional to principle quantum number's square.

So, from the above explanation we can conclude that the the energy of the fourth Bohr orbit of hydrogen atom will  be = (-328/4) = -82 kj/mol.

So, from here we get to know that when the an electron jumps from higher orbit, here fourth orbit to the lower orbit or here the second orbit, it absorbs energy which is calculated as -82 kj/mol energy.
