Bond Types

Courtney SoRelle- 6th Period

There are 3 types of bonds: Ionic, Metallic, and Covalent.

Ionic-

Combination of a metal and a nonmetal

Falls between  1.7- 3.3 on the Electronegativity Difference Scale

Characteristics: Dissolves in water, high melting temperature, doesn't conduct in solids, but conducts in liquids and dissolved.


Metallic-

Combination of a metal and metal

Characteristics: shiny, doesn't dissolve, high melting point, always conducts electricity


Covalent-

Combinations of a nonmetal and a nonmetal

Nonpolar Covalent fall between 0.0 and 0.3 on the Electronegativity Difference Scale

Polar Covalent fall between the 0.3 and 1.7 on the Electronegativity Difference scale

Characteristics: sometimes dissolves doesn't, low melting point, never conducts electricity
