Atomic Structure Worksheet 1
Use the name examples below to help you name the atoms and ions. See if you can figure out the
name differences between cation names and anion names or use your textbook for further help.
Use the information given on table below to calculate atomic mass. If not enough information is given
on the table below then go to the periodic table to find the atomic mass. Round all atomic masses to
the nearest whole number.
