In `SF_(6)` molecule,is formed in `n^(th)` excited state of '`S`'.What is n?

A hydrogen atom in the 4th excited state, then:

The bond order of a molecule in the excited state can be

The mangnitude of pontential energy of electron in n^(th) excited state of He^(+) ion is (8)/(81) time the kinetic energy of electron of excited state of Li^(2+) ion. Find 'n'

In a hydrogen atom, the electron is in n^(th) excited state. It may come down to second excited state by emitting ten different wavelengths. What is the value of n ?

In SF_(4) molecule, S involves ……………hybridisation.

Total number of spectral in UV region during transition from 5 ^(th) excited state to 1^(St) excited state

Statement 1: SF_(6) molecular has octahedral geometry Statement 2: Sulphur atom in SF_(6) molecule is in sp^(3)d hybridisation state.

The electron in hydrogen atom in a sample is in n^(th) excited state, then the number of differrent spectrum lines obtained in its emission spectrum will be
