Quantum Numbers and Orbitals

How many Quantum Number do we assign to an electron

4

What are the four Quantum Number that we assign to an electron?

Principal Quantum Number (n), Angular Momentum Number (𝓁), Magnetic Quantum Number (m_𝓁), Spin Quantum number (m_s) 

Principal Quantum Number (n)

Written with an integer 1, 2, 3 … shows size and energy by telling what shell it is in.

Angular Momentum Number (𝓁)

Written as integer from 0 to (n-1) defines shapes through sub levels.

What sub levels are shown in Angular Momentum Number (𝓁)?

s p d f

s

0

p

1

d

2

f

3

What 𝓁 values are possible is n=2

1 0

What 𝓁 values are possible is n=3

2 1 0

Magnetic Quantum Number (m_𝓁)

Written as an integer ranging from -𝓁 to positive 𝓁. Shows orientation of the orbital in space around the nucleus. (x plane, y pane, z plane)

What are possible m_𝓁 values with a p orbital

1 0 -1

How many electrons can a orbital have?

Spin Quantum number (m_s)

Either +1/2 or -1/2 showing wither a spin up or down.
