Question Answer
Atomic ElementElement whose particles are single elements. Most elements on the periodic table are atomic elements
Molecular ElementsElements whose particles are multi-atom molecules (diatomic). 7 diatomicHydrogen, Nitrogen, Oxygen, Fluorine, Chlorine, Bromine, Iodine.
Molecular CompoundsCompounds whose particles are molecules made of 2 or more nonmetals.
Ionic CompoundsCompounds whose particles are cations and anions. Most common in lab setting. Formed from metal and nonmetal. Always contains positive and negative ions coming together.
Arrhenius AcidsMolecular compounds that often behave as ionic compounds in water. Hydrogen and nonmetal. Hydrogen is usually listed first. Maybe binary contain 2 elements (HCl) or oxyacid contains oxygen (H2SO4)
How to name Type II Binary Ionic CompoundsName metal cation first (charge of metal cation) nonmetal base second. Name of nonmetal changed to -ide)
BerylliumBe
Nitride and what charge?N^3-
NeonNe
Aluminum and what charge?Al3
Sulfide and what charge?S^2-
Potassium and what charge?K1
Manganese and what charge?Mn2
NickelNi
TinSn
MercuryHg
HeliumHe
BoronB
Oxide and what charge?O^2-
Sodium and what charge?Na1
Name the 2 types of metal cationsType I metals whose ion can only have 1 possible charge (grp 1A/2A) and Al, Ga, Zn, Ag, Cd. Type II metal can have more than one possible charge. Determine charge by the charge on the anion.
StrontiumSr
SiliconSi
Barium and what charge?Ba 2+
CobaltCo
Silver and what charge?Ag1
GoldAu
Phosphide and what charge?P^3-
How to name binary ionic compoundsName of cation (metal)+ base name of anion (change end to -ide)

How to write Binary AcidsHydro prefix+nonmetal name (change ending to -ic) + write the word Acid
How to write Oxyacidsif polyatomic name ends in -ate, then change to -ic. if poly name ends in -ite, then change to -ous. Write the word Acid. Do not use Hydro- as the prefix.
