Covalent Bonding

Covalent Bonding. Covalent Bonding. A covalent bond is when valence electrons are shared between two atoms with high electronegativity ( nonmetals) . A molecule is a neutral group of atoms held together by covalent bonds.

POLARITY

POLARITY. POLAR BONDS Bonds between atoms POLAR MOLECULES Polarity between molecules Occurs when polar bonds create a dipole moment. Bond Polarity. HCl is POLAR because it has a positive end and a negative end. Cl has a greater share in bonding electrons than does H.
