Bonding
Bonds are formed when two atomic nuclei attract the same Electron/s.
bonding fast facts
Bonding in a Nutshell
Energy is released when a bond is formed because atoms acquire a more stable configuration by bonding.
Bonding creates a completed outer shell
Energy must be supplied to break a bond (activation energy)
Ionic Bonding
Result of the transfer of electrons
An atom that gains an electron becomes an anion which is a negative ion
An atom that loses an electron becomes a cation a positive ion
Examples are Na+, Ca++, and Cl-
Covalent Bonding
Result of when atoms are shared
The resulting structure is called a molecule
Single, double, and triple bonds occur when two atoms share 1,2, and 3 pairs of electrons respectively.
Polar and Nonpolar
Polar molecules have an unequal sharing of electrons
Nonpolar molecules include a equal sharing of electrons
