Part A)How much energy does the electron have initially in the n=4 excited state? Express your answer with the appropriate units.

Part B) In the Balmer-Rydberg equation, what value of m is used to determine the wavelengths of the Balmer series?

Part C) If our eyes could see a slightly wider region of the electromagnetic spectrum, we would see a fifth line in the Balmer series emission spectrum. Calculate the wavelengthλ associated with the fifth line.

Express your answer with the appropriate units.

Expert Solution

The energy of an electron in the level "n" is:

So:

The Balmer - Rydberg equation is:

Where: m=4. So: the Balmer-Rydberg equation is:

The equation for the Balmer series is:

So, for n=3,4,5 .....

All of these wavelenghts belongs to the visible region.

.........ultraviolet

An electron in a hydrogen atom is excited from the n = 1 ground state to the n = 4 excited state

An electron in a hydrogen atom is excited from the n = 1 ground state to the n = 4 excited state. Classify the statements about this absorption and emission process as true or false. True On average, the electron is closer to the nucleus in the n = 4 state than in the n = 1 state. The wavelength of light absorbed when the electron is excited from the ground state to n = 4 is the same as the wavelength of...

A hydrogen electron, initially in its second excited state (n=3), jumps down to the ground state n=1. The energy of n=1 state is -13.6 eV. A) What is the energy of the photon emitted from this jumping down process? ( I got 12.08889eV) B) Is this emitted photon energetic enough to create photoelectrons from Ni( Ni working function is 5 eV)? C) If this emitted photon (from the jump down from n=3 to n=1) is reabsorbed by a hydrogen electron...
