Do you know how to write the formula of an ionic compound?
Lewis Dot Structure, or Cross Products
Do you know how to name ionic compounds?
Write the metal, then put -ide on the end of the nonmetals
What are the properties of ionic compounds?
Crystal Structure, High Melting Points, Electrical Conductivity, and Solubility
Covalent bond:
chemical bond formed when two atoms share electrons
Double Bond
two atoms share two pairs of electrons
Triple bond:
atoms share three pairs of electrons
Molecular compound:
a compound composed of molecules
Polar Bond
electrons are shared unequally
Nonpolar Bond:
electrons shared equally
How do covalent bonds form?
Nonmetal and Nonmetal
Do you know how to write the formula of a covalent compound?
Lewis Dot Structure
Do you know how to name covalent compounds?
Prefix needed; include mono, on second element; add -ided to the end of the second metal; nonmetal on the left goes first
What are the three properties of covalent compounds?
Low Melting and Boiling Points, Poor Conductivity, Solubility
What is the difference between a polar and nonpolar bond?
Polar: electrons shared unequally
Examples: H20, HF
Nonpolar: electrons shared equally
Examples: F2, CO2
Metallic bond:
an attraction between a positive metal ion and electrons surrounding it
