Atoms vs. Ions worksheet
Cations
Anions
Have a positive charge because they
__________________ electrons
Have a negative charge because they
__________________ electrons
Ion symbol
To write the ion symbol, you must write the element symbol with the charge written on the top right.
Example: Ca2+, Zn2+, Ag1+
For each box, use the Bohr diagram to show the number of electrons in a standard atom. Then, you will need to
determine if the atom would lose or gain electrons and draw the Bohr diagram to show the number of
electrons in the ion. The first one has been done for you.
