Characteristics of Compounds
These are the two types of compounds
Molecular and ionic compounds
-ide
This type of elements is named using the stock system
Transition metals
OH- is the formula for this polyatomic ion
hydroxide
These are the types of elements that make up
1) Molecular compounds
2) Ionic compounds
What are
1) Nonmetal and nonmetals
2) Metal and nonmetal
This is the difference between naming molecular and ionic compounds
Molecular compounds use prefixes to denote the number of atoms, ionic does not
This is how you write the oxidation state of a given transition metal using the stock system
This is the formula for nitrate
NO3-
These are the types of bonds that are found in
1) molecular compounds
2) ionic compounds
1) Covalent bonds
2) No actual bond, just electrostatic interactions
K2S
Potassium sulfide
This is how you determine the oxidation state of a transition metal given the formula
eg. FeCl2
Look at charge. Chlorine is -1, so -1 x 2 = -2, therefore iron must be +2
Or, reverse the subscripts and look at charge that way!
PO43- is a polyatomic ion that can form H3PO4. This is the type of acid that forms when a polyatomic ion such as PO43- is joined with hydrogen
Oxoacid
This is how electrons behave in covalent and ionic bonds
Shared pair of electrons in covalent bonds (1 electron from each element)
Transfer of electrons in ionic bonds
PBr3
Name the following compound
CoBr3
Cobalt (III) bromide
This is the formula for
sodium sulfate
Na2(SO4)
These are drawings of the bonding between
1) H2O
2) NaCl
1) Drawing
2) Na+ Cl-
This is the name of this compound
C2H6
Bonus points for giving the name or type of bond according to organic chemistry
dicarbon hexahydride
or
ethane, an alkane bond
This is the formula for chromium (II) sulfate
CrSO4
This is the formula for phosphite and perphospate
Hint: phosphate = PO43-
phosphite = PO33-
Pernitrate = PO53-
