he gave the idea that of wave motion of electron

Erwin Rudolf Schrodinger

He formulated the shordinger equation

Erwin Rudolf Schrodinger

In which electrons are treated as moving with wave like motion in 3D space around the nucleus

Schrodinger equation

The solution of Schrodinger equation gave a set of numerical values called the

quantum numbers

explained the arrangement and movement of electrons, spectral lines of polyelectronic atoms and gave an acceptable model of an atom

Quantum Numbers

The 4 Quantum Numbers

An Electrons Address

it specifies the main energy level or orbit, it tells you the shell.

Principal Quantum Numbers

The bigger the number

The farther from the nucleus which means higher energy

values are n = 1,2,3,4

Principal Quantum Numbers

the 4 quantum numbers

Principal

Azimuthal

Magnetic

Spin

It gives you the information about the sub energy level or orbital. It tells you the shape of the orbital

Azimuthal Quantum Numbers

comes from the electrons angular momentum which is basically how an electron behaves when it moves around the nucleus as a wave

Azimuthal

these are the spatial orientations of an orbital, basically which direction the room is facing

Magnetic Quantum Number

The values are -l to +l

Magnetic Quantum Numbers

this is the spin of the electron, like whether its spinning clockwise or counter clockwise

Spin Quantum Number

Each orbital can hold _ electrons and they must have opposite spins

2 electrons

The values for this quantum number are : ½ and -1/2
