Guided Notes

18 min

Key concepts students will learn:

  • The periodic table organizes elements by increasing atomic number, and elements in the same group or family have similar chemical properties.

  • Metals are typically shiny and good conductors of heat and electricity, while nonmetals generally lack these properties and are located on the upper right of the periodic table.

  • Dmitri Mendeleev organized elements by atomic mass and predicted the existence of undiscovered elements, while Henry Moseley later reorganized the table by atomic number.
