1. Look at the compounds listed under Ionic Bonds.
Group 1 & 2 both show different compounds made by bonding different elements together. We will study 2 types of bonds. Let’s take a closer look at the elements in each compound to see what makes a compound IONIC or MOLECULAR (COVALENT).
Look at the compounds listed under Ionic Bonds.
List the first element in each compound. Look up the location of these elements. To what category do they belong – metal or nonmetal?
List the second element in each compound. Look up the location of the elements. To what category do they belong – metal or nonmetal?
Look at the compounds listed under Covalent (Molecular) Bonds. Repeat steps a & b above for this set of molecules.
Based on your answers above, what patterns are you noticing?
