Chemical  Bonds


Chemical bond- mutual electrical attraction between the nuclei and valence electrons of different atoms that bunds the atoms together


Ionic bonding- chemical bonding that results in the attraction between cations and anions.

Characteristics-

1-) dissolves (in water)

2-) high melting point

3-) conducts only as a liquid (not a solid)



Covalent bonding- results from the sharing of electron pairs between two at

Nonpolar covalent bond- when the bonding electrons are shared equally by the bonded atoms resulting in a balanced distribution of electrical charge.

Polar covalent bond- when the bonded atoms have an unequal attraction for the shared electrons

Characteristics-

1-)usually dissolves (in water)

2-)low melting point

3-) never conducts



Metallic bonding- chemical bonding that results from the attraction between metal atoms and the surrounding sea of electrons

Characteristics:

1-) shiny

2-)high melting point

3-) always conducts
