What are the names of the elements?
They are: hydrogen (H), oxygen (O), nitrogen (N) and carbon (C). The Periodic Table of Elements is arranged in rows called periods. Columns in the chart are grouped together by similar properties like gases, metals and earth. The number in each box is the number of atoms and the letters are the abbreviation for the symbol.
