IONS WORKSHEET
Name: __________________
Directions: For the following atoms,
a) draw the Bohr-Rutherford diagram for the normal atom and then, b) draw the Bohr-Rutherford
diagram for the ion it will form. Remember each ion is trying to get to a full valence orbit!
c) Write the symbol of the ion you created including the correct charge it has (ex. Mg2+).
