Types of Compounds

Types of Chemical Bonds

Chemical bonds provide the "glue" that holds Compounds together. Chemical bonds can also be described as the the forces that hold the atoms in cmpounds together.

​

Chemical Bonds

The two types of chemical bonds found in compounds are Ionic Bonds and Covalent bonds

​

Chemical Bonds

Ionic Bonds are formed when metals and nonmetals come together. This bond is an attraction between positive and negative charrges

Ionic Bonds

In an Ionic Bond a metal TRANSFERS 1 or more electrons to an Nonmetal. The metal then becomes positive and the nonmetal becomes negative

Ionic Bonds

For a compound to be ionic there must be at least one metal and 1 nonmetal present in the molecule

​

Ionic Bonds

Covalent Bonds are formed when 2 or more nonmetals come together.

"Co" means to share
"Valent" means valence electrons

Covalent Bonds

For a compound to be covalent there must only be nonmetals present in the molecule.
Covalent compounds are also called MOLECULAR Compounds

​

Covalent Bonds

Molecular or Covalent = only nonmetals

IONIC = metal and nonmetals
