1 Learning Objectives: To understand what is meant by the term, ‘relative atomic mass’

2 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 23 11 Mass number

3 Find the Ar values of the following: NaAr SCa FeN MnMg CCu OBr HF 23 Reset 32 56 55 12 16 1 40 14 24 64 80 19 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
