11TH GRADE AS-LEVEL CHEMISTRY: RELATIVE ATOMIC MASSES

In the previous class, we discussed the atomic structure. We emphasized the description of the type, number, and distribution of the fundamental particles which make up an atom. We also talked about some of the impacts these have on some atomic properties.

In this lesson, you will learn the definition and usage of the terms relative atomic, isotopic, molecular, and formula masses, based on the ¹²C scale.

This lesson must be completed before we meet on Friday when we’ll discuss what you learned so far. You will also turn in your presentations.
