How do you tell if a photon is emitted or absorbed?
The color of the light emitted would result from the amount of energy as it moves through shells. Absorption is shown by the energy levels increasing as the photon gains energy. The wavelengths shown relate to the amount of energy in the photon.

Can a hydrogen atom absorb a photon whose energy is greater than 13.6 eV?
Assertion: A hydrogen atom cannot absorb a photon whose energy is greater than 13.6eV, its binding energy. Reason: The extra energy will manifest as KE of the electron.
Can a hydrogen atom absorb a photon?
Can a hydrogen atom absorb a photon whose energy exceeds its binding energy? Solution : Yes, it can absorb.
How much energy does a hydrogen atom absorb?
Electrons in a hydrogen atom must be in one of the allowed energy levels. If an electron is in the first energy level, it must have exactly -13.6 eV of energy. If it is in the second energy level, it must have -3.4 eV of energy. An electron in a hydrogen atom cannot have -9 eV, -8 eV or any other value in between.

What photon energy is required to excite the hydrogen electron?
If a photon with a wavelength of 121.6 nm, and consequently, an energy of 10.2 eV interacts with an electron in a hydrogen atom, it will be absorbed by the electron, raising the electron to the first excited state.
How much energy is needed to excite an electron?
The energy required to ionize the atom is 13.6eV. Therefore, the energy required to excite the atom to the third excited state is 12.75eV, and the energy required to ionize the atom is 13.6eV. Note: The total energy of the electron is negative due to very strong electrostatic and atomic forces acting on it.
How much energy is needed to completely remove an electron from N 2 in a hydrogen atom?
Hence, the energy required to remove an electron from $$n=2$$ state in hydrogen is +3.
How much energy is required to take a hydrogen atom in its ground state?
THE VALUE OF GROUND STATE ENERGY OF HYDROGEN ATOM IS -13.6eV.
Which of the following can excite a hydrogen atom in ground state?
Answer : An electron having 11eV kinetic energy. Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams. What energy in eV will be required to excite the ground state electron of a hydrogen atom to h = 3 state ?
How much energy does it take to ionize a hydrogen atom that is in its third excited state?
For hydrogen atom in 3rd excited state, the energy is E_3=13.6/3^2 eV and similarly for hydrogen atom in 1st excited state, the energy is E_1=13.6/1^2 eV.
How much energy does the electron have initially in the N 4 excited state?
Because n here equals 4, the electron is in the fourth shell. Here we plug that in so we’re going to plug in -2.18 x 10^-18 joules/atoms and that’d just be 4 squared which is 16. When you do that, you’ll get -1.36 x 10^-19 joules/atoms. This would be its potential energy of that electron.
What is the change in energy if the electron from Part A now drops to the ground state?
The change in energy if the electron drops to the ground state is -2.04×10-18 J.
What is the value of in the ground state?
This function is known as the 1s atomic orbital. For hydrogen (H), an electron in the ground state has energy −13.6 eV, relative to the ionization threshold. In other words, 13.6 eV is the energy input required for the electron to no longer be bound to the atom.
What does ground state electron configuration mean?
The ground state electron configuration is the arrangement of electrons around the nucleus of an atom with lower energy levels. The electrons occupying the orbitals of varying energy levels naturally falls towards the lowest energy state or ground state.

What is the lowest energy state of an atom?
ground state
What is the difference between the ground state and the excited state of an atom?
The ground state configuration is the lowest energy, most stable arrangement. An excited state configuration is a higher energy arrangement (it requires energy input to create an excited state). Valence electrons are the electrons utilised for bonding.
What does the ground state of an atom represent?
A ground-state atom is an atom in which the total energy of the electrons can not be lowered by transferring one or more electrons to different orbitals. That is, in a ground-state atom, all electrons are in the lowest possible energy levels. eg: Consider a carbon atom whose electron configuration is the following.
What happens when electrons move from excited state to ground state?
When an atom is in an excited state, the electron can drop all the way to the ground state in one go, or stop on the way in an intermediate level. Electrons do not stay in excited states for very long – they soon return to their ground states, emitting a photon with the same energy as the one that was absorbed.
Why do electrons prefer the ground state?
The ground state is the lowest energy state of any molecule. When an electron is in the ground state, it has minimized its energy. Minimized energies give stable particles. Lots of chemistry particles like stability.
