1.5: Classifying Compounds Flashcards
What are the 3 classes of compounds that are possible?
nonmetal-nonmetal, metal-metal, nonmetal-nonmetal
Define ionic compounds
metal-nonmetal (NaCl), solids only in SATP
Define molecular compounds
nonmetal-nonmetal (SO2)
Define alloys
metal-metal combinations
Define acids
solids, liquids, or gases as pure compounds at SATP that form conducting aqueous solutions that make blue litmus paper red, only do this while dissolved in water
Define bases
compounds whose aqueous solutions make red litmus paper turn blue
Define neutra
do not affect litmus paper at all
Define polyatomic ions
ions containing a group of atoms with a net positive charger or a negative charge
Define formula unit
an ionic compound is a representation of the simplest whole number ratio of ions
Define empirical formula
another name for the simplest formula unit
Define hydrates
are compounds that decompose at relatively low temperatures to produce water an associated compound
