What are the rules for writing formulas for ionic compounds? Covalent compounds? G. Rank the bond types in order of strongest to weakest: ionic, nonpolar, metallic and polar.
H. How can you tell what of bond forms between two atoms? I. Explain how intermolecular forces are different then intramolecular forces? Why are both important? J. Rank the 4 bond types in order of highest melting and boiling points to lowest melting and boiling points. Explain why some molecules require more energy to melt/boil then others. K.
