Unit 10 ¨C Structure of the Atom - Objectives

Students can analyze data to explain the trends of atomic radii, ion size, ionization

energy, and electronegativity as seen on the periodic table. They will also

understand the role of valence electrons in bonding and can diagram bonding using

Lewis Dot structures and valence shapes.

Group and Period Trends: Why? Bohr Diagrams

It is helpful to look at Bohr diagrams of atoms up a group and across a period to understand why the

periodic trends exist. Please draw a Bohr diagram of each of the following atoms in the box indicated

and use the drawings along with the Group and Period Trends Why? activity to determine why the

periodic trends are what they are.

Chemistry ¨C Unit 11 Worksheet 1

Ionization energy

Plot graphs of successive ionization energies for B, Si, and Ca.

1. Compare the graphs ¨C what are the common features? What are the

differences?

2. Group the electrons for each element based on ionization energies. How many

electrons are in each group? You can change the scale of the vertical axis to

better differentiate between groups.

3. Is there a maximum number of electrons that can fit in each group? If so,

what is it?

4. Plot graphs of successive ionization energies for a few more atoms. Does the

evidence support your answer to #3?

5. Summarize the patterns you found in the table of successive ionization

energies.
