Question: Can A Hydrogen Atom Absorb A Photon Having Energy More Than 13.6 EV?

What happens when an electron emits a photon?

When an electron is hit by a photon of light, it absorbs the quanta of energy the photon was carrying and moves to a higher energy state.

Electrons therefore have to jump around within the atom as they either gain or lose energy..

What energy would be needed to remove the electron from the N 4 level of the hydrogen atom?

What energy would be needed to remove the electron from the n=4 level of the hydrogen atom? E=13.6 ⋅142eV=0.85eV=1.36⋅10−19J.

What causes a photon to be emitted?

A photon is produced whenever an electron in a higher-than-normal orbit falls back to its normal orbit. During the fall from high energy to normal energy, the electron emits a photon — a packet of energy — with very specific characteristics. … A sodium vapor light energizes sodium atoms to generate photons.

Can an electron absorb more than one photon?

The electrons can not absorb more than one photon to escape from the surface, they can not therefore absorb one quanta and then another to make up the required amount – it is as if they can only embrace one quantum at a time. If the quantum absorbed is not of sufficient energy the electron can not break free.

Can a free electron emit a photon?

A free electron cannot absorb a photon as it is not possible to satisfy the energy and momentum conservation simultaneously. … In Compton effect we have both electron and a photon as the final product and it is then possible to conserved energy and momentum.

How do you tell if a photon is emitted or absorbed?

The lines on the atomic spectrum relate to electron transitions between energy levels, if the electron drops an energy level a photon is released resulting in an emission line and if the electron absorbs a photon and rises an energy level an absorption line is observed on the spectrum.

Can a hydrogen atom absorb a photon whose energy exceeds its binding energy 13.6 eV?

Can a hydrogen atom absorb a photon whose energy exceeds its binding energy? … Yes, it can absorb.

Can atoms gain energy by absorbing a photon?

The electron can gain the energy it needs by absorbing light. … The atom absorbs or emits light in discrete packets called photons, and each photon has a definite energy. Only a photon with an energy of exactly 10.2 eV can be absorbed or emitted when the electron jumps between the n = 1 and n = 2 energy levels.

Can the electron in the ground state of hydrogen absorb?

Because an electron bound to an atom can only have certain energies the electron can only absorb photons of certain energies. For example an electron in the ground state has an energy of -13.6 eV.

Will the light be absorbed or emitted?

When the electrons return to lower energy levels, they release extra energy and that can be in the form of light causing the emission of light. On the other hand, absorbed light is light that isn’t seen. Absorption occurs when electrons absorb photons which causes them to gain energy and jump to higher energy levels.

How do you calculate the number of photons absorbed?

According to the equation E=n⋅h⋅ν (energy = number of photons times Planck’s constant times the frequency), if you divide the energy by Planck’s constant, you should get photons per second. Eh=n⋅ν → the term n⋅ν should have units of photons/second.

Can the electron in the ground state of hydrogen absorb a photon of energy greater than 13.6 eV?

Yes, a hydrogen atom in the ground state can absorb a photon of energy less than 13.6 eV.
