Ionic compounds
Ionic bonds are all…
Crystals like salt &
Electrically neutral
Ionic compounds composed of
Cations (metal)
Anions(nonmetal)
Ionic compounds are electrically
Neutral
Cations
Positive
Anions
Negative
The electrostatic forces that hold ions together in ionic compounds are called
Ionic bonds
A chemical formula shows
The kinds an number of atoms in the smallest representative unit of a substance
A formula unit is the —— whole number ratio of —- in an —–compound
Lowest
Ions
Ionic
Most ionic compounds are crystalline solids at
Generally have high
Room temperature
Melting points
Ionic compounds can conduct an electric current when
Melted or dissolved in water
The coordination number of an ion is the number of ions of opposite charge that surround the ion in a
Crystal
Ionic compounds and ionic bonds only form between
a metal and nonmetal
