Quantum Model - Wavefunction values

Question 1

What is n? What does it determine?

Answer 1

The principle quantum number

It determines the shell (1s, 2s, 3s, etc)

Question 2

What is l? What does it determine?

Answer 2

The orbital angular momentum quantum number

It determines the subshell (2s, 2p, 2d, etc)

Question 3

What value can l have?

Answer 3

0 to n - 1

Question 4

What is m_l? What does it determine?

Answer 4

The magnetic quantum number
