Question

Energy of second bohr orbit of the hydrogen atom is -3 28 kilo joule per mole hence energy of fourth bohr's orbit will be

Answer 1

Answer:

The answer will be −82 kilo joule per mole

Explanation:

In the hydrogen atom the second bohr orbit has energy of -328 kilo joul per mole

Now according to the formula,

en=e1/n^2   [ where n is the number of orbit]

Therefore, for second orbit

e2=e1/(2)^2 =−328 kilo joule per mole

e1=−328×4  kilo joule per mole

Therefore for the fourth orbit,

e4=e1/(4)^2

=−328×4/(4)^2 kilo joule per mole

=−82  kilo joule per mole
