Chemistry and chemical reactivity 9th edition kotz test bank by Spzz - IssuuKey topics are the structure of the atom and related information atomic number, isotopes , the mole unit, the periodic table, chemical formulas and names, and the relationships between formulas and composition. Three to five class periods will probably be necessary in order to address the essentials in this chapter unless your students are well-versed in some of these topics. They are often uneasy about being given this choice. We certainly emphasize that they will see other possibilities and that even negative charges are possible but that they will not see them in the general chemistry course. They can be reminded that correct names and formulas are required to prevent serious consequences, such as the use of the wrong medicine which can have tragic results or the purchase of the wrong substance which leads to wasted resources. Properties of Elements Take as many samples of elements as possible to your lecture on the elements and the periodic table.
