When do electrons emit energy?

Higher frequency wavelengths will elevate electrons in the atom to higher energy levels. After elevation to a higher energy state and circling the atom once, the electron will emit a photon of lower energy and decay to the ground state.

Explanation:

Whenever an electron jumps from higher energy state to lower energy state it emit out energy in the form of electromagnetic radiation.

The amount of energy liberated or emitted after the transition is determined by the help of Rydberg's Equation:

[tex]\frac{1}{\lambda}=R_H\left(\frac{1}{n_i^2}-\frac{1}{n_f^2} \right )[/tex]

Where,

[tex]\lambda[/tex] = Wavelength of radiation

[tex]R_H[/tex] = Rydberg's Constant

[tex]n_f[/tex] = Higher energy level =

[tex]n_i[/tex]= Lower energy level

Energy is related to wavelength that is Planck's equation:

[tex]E=\frac{hc}{\lambda}[/tex]

[tex]\lambda[/tex] = Wavelength of radiation

E= energy emitted by the electron on transition
