Compounds Flashcards
What are molecular compounds

How to tell if an element is a compound
If it is made up of different elements
How to tell from chemical formula that the compound is ionic
If the compound is the binding of a non-metal with a metal, it is ionic
How to tell from chemical formula that the compound is covalent
If the compound is the result of the binding of two non-metals
what are molecular elements
a pure substance composed of two or more atoms of the same element
what are polyatomic ions
ions which consist of more than one atom (example, O3)
what are polyatomic ionic compounds
Compounds made up of ionic bonds (i.e. metal and non-metal) and polyatomic ions (i.e. ions consisting of more than one atom) Example: CaCO3 or NaOH
