Question

The Bohr model of the atom explained why emission spectra are discrete. It could also be used to explain the photoelectric effect. Which is a correct explanation of the photoelectric effect according to the model? Electrons are emitted with more speed when brighter light strikes them. Electrons need small amounts of energy to be released from an atom. Electrons move between levels only if they are hit by the right frequency of light. Electrons need specific amounts of energy to jump levels and be emitted.

Answer 1

electrons need specific amount of energy to jump levels and to emit energy

Answer 2

Electrons need specific amounts of energy to jump levels and be emitted.

Step-by-step explanation:

According to Bohr's model, electrons are in quantified orbits. That is, they can only jump to higher energy levels if the energy of the absorbed photon is equal to or greater than a certain value. Therefore, if an electron absorbs the energy of a photon and it has more energy than a certain defined quantity for each material, the electron is emitted.
