Trends or Periodicity

The periodicity of these properties follows trends as you move across a row or period of the periodic table or down a column or group:

Moving Left → Right

  • Ionization Energy Increases
  • Electronegativity Increases
  • Atomic Radius Decreases

Moving Top → Bottom

  • Ionization Energy Decreases
  • Electronegativity Decreases
  • Atomic Radius Increases

Tips to study the modern periodic table

  • Print out a copy of the periodic table and stick it near your study desk.
  • Breakdown the table into smaller sections to learn it. Most charts are already divided by color and type of element. You could go by row, column, atomic weight, or simply easiest to hardest. Find patterns that stick out to you.
  • Start with the s-block elements first. Then try to learn the p-block elements groupwise. Later, start learning lanthanides and actinides.
  • Keep a copy of a periodic table in your wallet. Try learning the periodic table when you get free time. For example, traveling by public transport or just waiting in the line for something.
  • Learn a few every day and always review the old ones! If you don't review and quiz yourself, you will forget.
  • You can also learn the periodic table by catchy song or a sentence.  You can either create your own or go on the internet.
  • Learn all the trends of the modern periodic table.
  • Refer to the chapter notes provided by
