The maximum number of electrons in all orbitals
![]()
Pauli Exclusion Principle
In a given atom no two electrons can have the same set of four quantum numbers (n, l, ml, and ms)
it is impossible for two electrons of a poly-electron atom to have the same values of the four quantum numbers: n, the principal quantum number, ℓ, the angular momentum quantum number, mℓ, the magnetic quantum number, and ms, the spin quantum number
What values can the Principal Quantum number assume
The principal quantum number has integral values: 1, 2, 3,…
What effect does n have on the size of the orbital and the energy of the electrons
As n increases, the size of the orbital increases (the electron spends more time farther from the nucleus).
As n increases, the energy of the electrons increases (the electron is less tightly bound to the nucleus, and the
energy is less negative)
What is the shape of all s AO? All s AO have spherical shape
p orbital
d orbital
f orbital
A node, or a nodal surface is an area of zero probability to find the electron.
What is meant by degenerate orbitals?
Degenerate orbitals are a group of orbitals with the same energy
electron repulsion have on the effective nuclear charge
