Which of the following determines the range of spectral lines produced during electron transition? . a. the total number of energy levels the electron can jump to.. b. the lower energy level to which the electron returns.. the higher energy level to which the electron jumps.. c. the number of electrons under electron transition at the same time..

A.The total number of energy levels the electron can jump to.

Explanation:

Spectral lines are bright or dark lines over continuous spectrum which occur due to emission or absorption of energy.

When an electron jumps to or from one energy level to another energy level, spectral lines are produced. The range of spectral lines depends on the number of energy levels available to which the electron can jump. This depends the amount of energy gained/lost by the electron.

Thus, the correct answer is: A.The total number of energy levels the electron can jump to.

e/c, where e is its total energy
