Covalent Bonds

Covalent bonds do not give and take electrons, they share electrons.

They are usually made up of 2 or more nonmetals.

A molecule is another name for a covalent bond between atoms.

In a covalent bond atoms may share one(single bond), two(double bond) or three(triple bond) pairs of valence electrons.

Covalent bonds(molecules) usually have low melting and boiling points,

Covalent bonds usually do not conduct electricity when dissolved in water.

Plastics and rubber are used to insulate electric wires because they are poor conductors of electricity.

A covalent bond where electrons are shared unequally is called a polar bond.

A covalent bond where electrons are shared equally is called a nonpolar bond.
