This graphing activity, Atomic Number vs. Ionization Energy, will help students grasp a very difficult, but critical, concept in chemistry. This graphing activity includes 3 graphing worksheets for varying levels of ability. Data sheets of the first 54 elements and their ionization energies are also included. A completed graph is included.
Students will observe how ionization energy changes from left to right across the periodic table and from top to bottom of a family. These worksheets will help your students grasp the following relationships:
1)The distance of the valence electrons from the nucleus and the number of shielding electrons determines the element's ionization energy.
2) The members of the families of elements that have a relatively high ionization energy;
3) The members of the families of elements that have a relatively low ionization energy.
This activity is part of a bigger bundle which includes a PowerPoint and worksheets on other periodic trends including electronegativity and atomic radius.
