Properties of ionic compounds
High boiling point High melting point Solid at room Conduct electric Soluble In water
Properties of molecular
Low boiling point Low melting point Gas or liquid at room temperature Do not conduct electric Soluble in organic solvent

How man quantum numbers are need to describe and electron
4
Principal symbol is giving what symbol
N
The energy level depends of n what does it do
If n ^ so does the energy level
N^=E^
Can n have both negative and positive values
No only positive
As the value of n increases the orbital what
Increases
As n increases the electron is like to be found where
Further away from the nucleus
Angular momentum quantum numbers
Symbol l
Has to be 1 lower then n
L=n-1
Is n is 3, l =0,1,2
Magnetic quantum number
Symbol ml
Can have numbers between +l and -l
If l=3, ml=-3 to 3
Can be looked at as orbitals
Spin quantum numbers
Symbol ms
Can only have values
Of 1/2 or -1/2
