LOUIS DE BROGLIE –
PRPOSED THAT THE ELECTRON (WHICH IS
THOUGHT OF A PARTICLE) COULD ALSO BE
THOUGHT OF AS A WAVE.
ERWIN SCHRODINGER
USED THE WAVE IDEA TO DEVELOP A
MATHEMATICAL EQUATION TO
DESCRIBE THE HYDROGEN ATOM.
HE DISCOVERED THAT ELECTRONS
MOVE AROUND THE NUCLEUS IN A
CLOUD NOT ORBIT.
WERNER CARL
HEISENBERG
DISCOVERED THAT FOR A VERY
SMALL PARTICLE LIKE THE
ELECTRON, ITS LOCATION
CANNOT BE EXACTLY KNOWN
AND HOW IT IS MOVING THIS IS
CALLED “UNCERTAINTY
PRINCIPLE” – CANNOT LOCATE
THE EXACT POSITION OF AN
ELECTRON AT ANY GIVEN TIME
(TOO SMALL, TOO FAST)
