A difference of 2.3 eV separates two energy levels in an atom. What is the frequency of m radiation emitted when the atom make a transition from the upper level to the lower level ?

Text Solution

Verified by Experts

Here `E=2.3eV = 2.3xx1.6xx10^(-19) J`
As E=hV
`therefore v=€/(h)=(2.3xx1.6xx10^(-19))/(6.6xx10^(-34))=5.6xx10^(14) Hz`

A difference of 2.3 eV separates two energy levels in an atom. What is the frequency of radiation emitted when the atom make a transition from the upper level to the lower level?

What is the wavelength of light emitted when the electron in a hydrogen atom undergoes transition from an energy level with n = 4 to an energy level with n = 2

(A) The electron in the hydrogen atom passes from energy level n = 4 to the n= I level. The maximum and minimum number of photon that can be emitted are six and one respectively. The photons are emitted when electron make a transition from the higher energy state to the lower energy state.

According to the Bohr theory for the atomic spectrum of hydrogen the energy levels of the proton -electron system depends, on the quantum number n. In an electron transition from a higher quantum level , n_(2) to the lower level n_(1) , radiation is emitted. The frequency, v of the radiation is given by h v = (E_(n_(2)) - E_(n_(1))) where, h is Planck.s constant and E_(n_(2)), E_(n_(1)) are the energy level values for the quantum number n_(2) and n_(1) . A useful formula for the wavelength, lambda = c//v is given by = lambda(Å) = (912)/(Z^(2)) xx ((n_(2)^(2)n_(1)^(2))/(n_(2)^(2)-n_(1)^(2))) where, Z = atomic number of any one electron species viz H, He^(+), Li^(2+), Be^(3+) ,..... For hydrogen Z=1 In the above formula, when n_(2) rarr oo , we have lambda = (912)/(1^(2)) xx n_(1)^(2) . This values of lambda is known as the series limit for the given value of n_(1) . Calculate the value of n_(1) for the series limit lambda = 8208 Å
