What two types of atoms make a covalent bond?

• 2 Nonmetals

• 1 Nonmetal and 1 Metal

• 2 Metals

• 2 Noble Gases

Covalent compounds

• Share electrons

• Transfer electrons

• Share electrons unequally

• Don't concern themselves with electrons

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

Predict the bond that will form between Cl and Cl.

• Ionic

• Covalent

What is a covalent bond?

• A bond formed by the sharing of electrons between atoms
