Bonding Basics

Why do bonds form?

• To fill the valence shell of electrons for the elements involved
• to release energy stored in the bonds
• because whenever you mix two chemicals, there will be a reaction
• because of attraction

A bond in which there is unequal sharing of electrons is 

• ionic
• polar covalent
• nonpolar covalent
• metallic

Atoms with a strong attraction for electrons they share with another atom exhibit

• zero electronegativity
• low electronegativity
• high electronegativity
• negative electronegativity
