how do you name ionic compounds

A

first part is metal name last part is non metal with ide

29
Q

how to name transition metal compounds

A

put metal first and then charge on it in roman numerals and then non metal with ide

30
Q

how to name polyatomic ion compounds

A

element name first then name of polyatomic ion

31
Q

naming covalent compounds

A

use prefixes for elements. if only one do not use mono for first element

32
Q

VSEPR rules

A

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

33
Q

what is electron geometry

A

the shape of the compound including the lone pairs on the central atom

34
