WHAT IS A CHEMICAL BOND?

AN ELECTRICAL ATTRACTION BETWEEN THE NUCLEI AND VALENCE ELECTRONS OF AN ATOM AND WHICH BINDS ATOMS TOGETHER.

THE OCTET RULE

The octet rule refers to the tendency of atoms to prefer to have eight electrons in the valence shell. 

IONIC BOND

TRANSFER OF ELECTRONS between METAL AND NON METAL (cation + anion)

COVALENT BOND

SHARING OF ELECTRONS (AMONG NONMETALS)

POLAR VS. NONPOLAR COVALENT BONDS

WHAT IS ELECTRONEGATIVITY?

A MEASURE OF THE TENDENCY OF AN ATOM TO ATTRACT ELECTRONS TOWARD ITSELF.

NONPOLAR 

ELECTRONS ARE EQUALLY SHARED BY THE BONDED ATOMS.

BALANCED DISTRIBUTION OF ELECTRICAL CHARGE

ELECTRONS SPEND THE SAME LENGTH OF TIME IN THE LOCALITY OF EACH ATOM.

POLAR

BONDED ATOMS HAVE AN UNEQUAL SHARING OF ELECTRONS (PARTIAL ELECTRON TRANSFER)
