Electronic Configuration Flashcards
What is hunds rule
Where degenerate orbitals are available they must fill single with parallel spins
What is aufbaus principle
Electrons fill orbitals in order of increasing energy
what is paulis rule
Orbitals can hold no more than 2 electrons and where there are 2 electrons they must have opposite spins
What does isoelectric mean
They have the same arrangement
What is the principle quantum number? (n)
The electrons main energy level eg. First shell n=1
What is the angular momentum number (l)
Orbitals found in s,p,d,f
S=0
P=1
What is the magnet quantum number (ml)
Space in the orbital
What’s the bond angle on a tetrahedral molecule
109.5
What’s the bond angle on a pyramidal molecule and lone pairs
3,1
107
What’s the bond angle on an angular molecule
104.5
What’s the name of the 5,0 molecule
triagonal bipyrimidal
