Honors Chemistry Podcast 4.2 Chemical Nomenclature and Formula Writing
Ionic Compounds • Formed from metals losing electrons to nonmetals resulting in ions of opposite charges. Na Cl
Nomenclature (naming) • Metal ion always goes first • Nonmetal ion changes name ending to –ide NaBr CaCl2
Name the following ionic compounds • Li2S • K3P • CaO • Sr3N2 • MgI2
Formula Writing • Metal (positive ion) first • Balance charge of ions to form a neutral compound • Examples: • Magnesium nitride Sodium Sulfide
Formula Writing • Write formulas for the following compounds: • Magnesium nitride • Potassium chloride • Lithium Sulfide • Rubidium oxide
Transition Metals • Elements with more than one possible charge (oxidation state)- use Roman numerals in name • Fe2(SO4)3 • FeSO4 • CuO • Cu2O
Transition Metals • Write the formula for the following: Manganese (II) oxide Cobalt (I) phosphide Titanium (II) bromide • Name the following: CuCl2 NiBr AuCl3
Polyatomic Ions • Name the following: Na2SO4 K3PO4 Mg(OH)2 • Write the formulas for the following: Titanium (II) hydroxide Potassium sulfite Calcium nitrate
