Indicate whether energy is emitted or absorbed when the following electronic transitions occur in hydrogen: (b) from an orbit of radius 0.529 to one of radius 0.476 nm

An electron in a hydrogen atom is excited with electrical energy to an excited state with n = 2. The atom then emits a photon. What is the value of n for the electron after the emission?

According to the Bohr theory of the hydrogen atom, what is the minimum energy (in J) needed to ionize a hydrogen atom from the n=2 state?

An electron in the n = 7 level of the hydrogen atom relaxes to a lower-energy level, emitting light of 397 nm. What is the value of n for the level to which the electron relaxed?

An electron in the n=7 level of the hydrogen atom relaxes to a lower energy level, emitting light with a wavelength of 93.1 nm. What is the value of n for the level to which the electron relaxed?

Calculate the wavelength of the light emitted when an electron in a hydrogen atom makes the transition from n=2 to n=1 using the Bohr model.
