When one electron moves from the 4th shell to the 2nd shell in hydrogen is energy absorbed or emitted by the atom?

The energy is absorbed by the electrons because work needs to be done on the electrons to raise them to an excited state. Energy is stored in the electrons while they are in their excited state and would emit energy if they returned to their ground state.

Is energy emitted or absorbed when an electron moves from an excited state to a ground state?
Emitted, and the precise amount of energy that is emitted will depend on what kind of atom, and moving from which excited state. That's how spectrographs can determine what element is present.
Which principal energy level change by the electron of a hydrogen atom will cause the greatest amount of energy to be absorbed?
n=2 to n=5 , hope that helps
What happens to beta alpha and gamma radiation after they are emitted?
they are absorbed, depositing their energy in whatever absorbed them.
Why is a shorter wavelength of light emitted when an electron falls from n4 to n1 than when an electron falls from n2 to n1?
The shorter the wave length the more energy. The further the electron falls, the more energy that will be emitted and the shorter the wavelength.
If an electron has absorbed energy and has shifted to a higher energy level the electron is said to be what?
This electron is called excited.
What does the electron produce when they change energy levels?
a photon is emitted or absorbed
Is energy absorbed when an electron moves to a closer shell?
No. Energy is emitted when an electron moves to a closer shell (closer to the nucleus).
Is energy emitted or absorbed when an electron moves from an excited state to a ground state?
Emitted, and the precise amount of energy that is emitted will depend on what kind of atom, and moving from which excited state. That's how spectrographs can determine what element is present.
When an electron drops from a higher energy state to a lower energy state?
A photon is emitted when an electron falls from a higher to lower orbital. A photon is an elementary particles, the quantum of light and all other forms of electromagnetic radiation.
How did Bohr explain the line spectrum of hydrogen?
The difference in energy between the energy levels determines color of light emitted when an electron moves from one energy level to another.
What is the highest energy photon that can be absorbed by a ground-state hydrogen atom without causing ionization?
yes , the electron in the ground state of the hydrogen atom will absorb a photon of energy 13.6ev but not greater than 13.6 ev . because 13.6 ev is the energy which excites the hydrogen atom

An electron that has absorbed energy?
excited state
What was Niels Bohr famous for?
Niels Bohr was involved with many aspects of the development of Quantum Mechanics but he is best known for his theory of the Hydrogen atom. In this theory he applied Planck's concept of quantization to the dynamics of the electron in the Hydrogen atom. He concluded that the electron could only have certain energies and light emitted from Hydrogen only occured when the electron dropped from a high energy level to a lower energy level. This theory fully explained the unusual light spectrum emitted by Hydrogen, which had puzzeled scientists for years.
Why is a shorter wavelength of light emitted when an electron falls from n4 to n1 than when an electron falls from n2 to n1?
The shorter the wave length the more energy. The further the electron falls, the more energy that will be emitted and the shorter the wavelength.
