Question

If same energy is supplied to ekectron in ground state of hydrogen as well as he+ electron jump to 5 shell in hydrogen then final prbit of electron in he + is

Answer 1

Answer:

Not quite sure about the answer .

Explanation:

Energy supplied to hydrogen is Higher energy levels energy - Lower energy levels energy

Higher energy levels energy(5) is -13.6/n^2

-13.6/5^2

-0.544eV

Lower energy levels energy is

-13.6eV

Energy supplied is

-0.544 - - 13.6

13.0564eV

Energy of H like atoms in the nth shell is

-13.6Z^2/n^2

For He , energy in ground state is

-13.6 * 4/1 is -54.4eV

when 13.056 eV is absorbed

Energy becomes -41.344

which orbit will have this energy ?

-41.344= -13.6* 4/ n^2

n^2 = 54.4/41.344 is 1
