Rules of orbital diagrams and electrons
What shape is the d orbital
clover
What shape is the p orbital
dumbbell
What shape is the f orbital
flower/complex
Hund's Rule
orbitals of equal energy are each occupied by one electron before any orbital is occupied by a second electron, and all electrons in singly occupied orbitals must have the same spin
What is the 3rd number in a quantum number
placement (-1-1)
What is the 4th number in a quantum number
spin (up=1/2,down=-1/2)
Pauli exclusion principle
states that a maximum of two electrons can occupy a single atomic orbital but only if the electrons have opposite spins
uncertainty principle
the idea put forth by Werner Heisenberg in 1927 that the behavior of subatomic particles is uncertain, suggesting that all of the physical laws governing the universe are based on uncertainty
Aufbau Principle
the rule that electrons occupy the orbitals of lowest energy first
What shape is the S orbital
Circle
What is the 1st nnumber in a quantum number
Energy level- 1-7
What is the 2nd number in a quantum number
Orbital level (s=0,p=1,d=2,f=3)
