4.6, 4.8 Flashcards
Ionic Compounds= Charge Neutral
contain positive and negative ions and in a chemical formula sum of + charges equals sum of - charges
Formula of Ionic Compounds
reflect smallest whole number ratio at ions
Basic Procedure to Write Ionic Compound Formula
Write symbol for metal cation and its charge followed by symbol for nonmetal anion and its charge then adjust subscript on each cation and anion to balance charge
Common Name
What we call Ionic compounds in day-to-day life like table salt
Systematic Name
Verbal version of the formula of the ionic compound
Categories of Ionic Compounds
Depend on the metal: metals that form 1 type of ion and metals that form more than 1 type of ion
Binary Compounds
Contain only two different elements
Names of Binary Compounds
(name of metal cation)(base name of nonmetal anion +ide)
Names of Binary Compounds with Transition Metals
(name of metal cation)(charge cation in roman numerals)(base name of nonmetal anion +ide)
Polyatomic ion
composed of two or more atoms
Oxyanions
anions containing oxygen and another element (most common polyatomic ions)
Two Ions in Polyatomic Series
less oxygen is -ate more oxygen gets -ite
2+ Ions in Polyatomic Series
hypo least oxygen -ite is less oxygen -ate is more oxygen and per is most oxygen
Hydrates
ionic compounds containing a specific number of water molecules associated with each formula unit
Water of Hydration
number of water molecules associated with each formula unit
