Name: ___________________________________ Date: ________________________ Bohr-Rutherford Diagrams – Forming Ions EXAMPLE: 20 Ca 2+ * This atom has a charge of 2+, it is called an ION. Draw a diagram. 40 1. Did Calcium gain or lose electrons to become an ion? EXAMPLE: Draw the Bohr-Rutherford diagram of the element Chlorine (Cl), and then the ion of chlorine (Cl-). 1. Did Chlorine gain or lose electrons to become an ion? Name: ___________________________________ Date: ________________________ PRACTICE: 1. Draw the following Bohr-Rutherford Diagrams, and calculate the ionic charge. Ionic Charge = # Protons - # Electrons Magnesium ion (Mg2+) Oxygen ion (O2-) Potassium ion (K+) # protons = # electrons = Ionic Charge = Sodium Ion (Na1+) # protons = # electrons = Ionic Charge = Calcium Ion (Ca2+) # protons = # electrons = Ionic Charge = Fluorine Ion (F1-) # protons = # electrons = Ionic Charge = # protons = # electrons = Ionic Charge = # protons = # electrons = Ionic Charge =
