Question

question 5 of 25 how does quantum theory explain the emission spectra of atoms? a. electrons gain and release energy in a slow, continuous fashion. b. a single, specific amount of energy is associated with each movement of an electron between energy levels. c. the movement of an electron between energy levels occurs gradually as small amounts of energy are absorbed. d. electrons absorb the energy they need to jump to a higher energy level from any light source.

Explanation:

Quantum theory states that electrons occupy discrete energy levels. When an electron moves between energy levels, it emits or absorbs a photon with an energy equal to the energy - difference between the levels. So, a single, specific amount of energy is associated with each electron movement between energy levels, which explains the discrete lines in emission spectra.

Answer:

B. A single, specific amount of energy is associated with each movement of an electron between energy levels.
