Lecture - How Atoms Form Ions

What are the period and group trends of different properties?

• Trends related to the periodic table layout

• Trends related to climate change

How are period and group trends in atomic radii related to electron configuration?

• They are not related at all

• They are related through chemical bonding

• They are related through the arrangement of electrons in shells and subshells

• They are related through the nucleus size
