Ionic compounds Flashcards
Are Ionic compounds conductive?
Conducts when molted or dissolved
Ionic compounds are composed of what elements
Non metals and metals
Hardness and melting point of Ionic compounds
Hard and ridged. High melting point
What are polyatomic ions
They are a group of atoms that behave like a single ion, they are in group three.
What are multivalent metals
They can form ions of different valences, ionic charges
Found in the first group, they use the IUPAC & classical systems
In a name or formula for an ionic compound, which elements come first. What happens to the ending of the last element?
The metal comes first, then the non metal. The ending of the non metal turns to “ide”
What is the IUPAC system
Ex. Copper (II) nitride
Turns to
Cu3N2
Use crisscross method
What is the classic (ous-ic) system
Ex. Stannous fluoride
Turns to
SnF2
Use the first table
Type of bond ( keeps ionic bonds together)
Ionic
What kinds of systems are used with covalent bonds
IUPAC
classical
What is an electrolyte
A solid or liquid that dissolves to conduct electricity, due to the presence of MOBILE IONS.
