ORBITALS I
Atomic orbital: contains
up to 2 e-
For atoms with more than one electron this
is the common spatial part of 2 spin orbitals
For atoms with more than one electron this
is the common spatial part of 2 spin orbitals
Spin orbital: contains 1 e-
y (spin orbital, 1 e- wavefunction)
Specified by four quantum numbers
y (spin orbital, 1 e- wavefunction)
Specified by four quantum numbers
Principal quantum number n
Angular
quantum number l
Magnetic
quantum number ml
Spin quantum
number ms = +½
or -½
Pauli exclusion principle:
No 2 e- in the same atom can have the same
4 quantum no’s.
No 2 e- in the same atom can have the same
4 quantum no’s.
