• The outer most electrons

• The inner most electrons

• The 2nd and 3rd electron to be added to the orbital

• The electrons that are pulled off due to frcition

In borhs model, Orbitals are also known as

• Elliptical

• Circles

• Energy levels

• not fixed motion

When an electron goes from a high level to its original energy level, it releases

• ENERGYYYYY

• I like turtles

• an electron

• a charge
