Form of electromagnetic radiation

Light

1

Four characteristics of electrons

Travel at the speed of light
Contain energy
Have an electric and magnetic component

Do not need a medium

2

Wave speed equals

Distance/time

3

Wave velocity equals

Frequency times wavelength

4

WHole number frequency

The particle theory

5

Electrons called photoelectrons are emitted from a metal surface when he light of certain frequency shines on the surface

Photo electric affect

6

Said matter was just another form of energy

Brogile

7

Said we cannot simultaneously know the location in velocity of an electron

Heisenberg

8

Had to quantum mechanical model of the Atom which treats electrons as waves

Schrödinger

9

Three dimensional region in space in which the electron is likely to be found

Atomic orbital

10

Arrangement of electrons in an atom

Electron configuration

11

Electrons will fill the lowest available energy level

Aufbau principal

12

And electron will want it's on orbital and will not pair up unless it has to

Hunds rule

13

Electron will only pair up with an electron of the opposite spin

Pauli exclusion principle
