Electron Transition

Can electrons move between energy levels?If so, how?

How are transition and light related?

Which energy level is present?

n = 2 n = 2 n = 3

Electron Transition• Electrons require energy to move between levels • e- in 1st orbital is held closer to nucleus and has

lower energy (ground state)• e- in 5th orbital is further from nucleus and has high

energy (excited state)• e- CAN MOVE between shells by absorbing or

releasing energy, called e- transition

Electron Transition

ELECTRON TRANSITION occurs as:

electron absorbs energy and moves away from nucleus

- called excited state

electron emits energy and moves towards nucleus

- called ground state
