how do you name ionic compounds
first part is metal name last part is non metal with ide
how to name transition metal compounds
put metal first and then charge on it in roman numerals and then non metal with ide
how to name polyatomic ion compounds
element name first then name of polyatomic ion
naming covalent compounds
use prefixes for elements. if only one do not use mono for first element
VSEPR rules
1) identify the central atom
2) count its valence electrons
3) add one electron for each bonding atom
4) add or subtract electrons for charge
5) divide the total of these by 2 to find the total number of electron pairs
6) use this number to predict the shape
what is electron geometry
the shape of the compound including the lone pairs on the central atom
molecular geometry
shape of the compound with only the atoms not lone pairs
in a double bond there are how many sigma and how many pi
1 sigma and 1 pi
in a triple bond how many sigma and pi bonds

single bond has what
1 sigma
formula for bond order
(bonding electrons-antibonding electrons)/2
diamagnetic
all the electrons are paired
paramagnetic
unpaired electrons
