How Did Quantum Theory Help Establish a Relationship between the Energy of an Electron and Its Position in an Atom?

it is not possible to describe both the velocity and location of an electron at the same time. This concept is known as the Heisenberg

principle

4 Quantum Numbers

How many quantum numbers are there?

Orbital Shapes

Electron Arrangment

Instead of using a number, a letter is used to represent the azimuthal quantum number:

ℓ = 0, 1, 2, 3, 4…

ℓ = s, p, d, f, g…

​The Azimuthal Quantum Number= (n-1)

The magnetic orbital quantum number (m_l) provides the orientation of the orbital shape along the x, y, and z axes

​

​The Magnetic Orbital Quantum Number

The magnetic spin quantum number (m_s) indicates the direction of spin of each electron. One electron spins clockwise and the other spins counterclockwise.

​The Magnetic Spin Quantum Number:
m_s: –½ and +½
