P4_Group+2

In this Unit, we have studied the relationship among periodic trends,types of chemical bonding and the properties of ionic and moleclar compounds. We have analyzed chemical reactions in terms of the type of reaction and the reactivity of starting materials. We use appropriate symbols and formulas to represnt the structure and bonding of chemical substances. Here are the notes for Unit One:
