TRANSCRIPT

Learning Objectives: To understand what is meant by the term, relative atomic mass Ar is the relative atomic mass. This is the mass of an atom relative to the mass of 12 C. This is easy: You just look it up on your Periodic Table in the exam. Na Mass number Find the Ar values of the following: NaAr SCa FeN MnMg CCu OBr HF 23 Reset Show instructions Hide instructions Click on each element to reveal answer Click on the large Periodic Table to shrink it Click on the Periodic Table to enlarge it
