PRESENTATION OUTLINE

1.

The periodic law

  • Mendeleev developed his periodic table before the discovery of protons.
  • He did not know that atoms of two different elements could not have the same number of protons.
2.

Periods

  • To understand the structure of the table think about what happens as the atomic number increases.
  • The one electron in a hydrogen atom and two electrons in a helium atom can fit in this orbital
3.

Groups

  • Each column on the periodic table is called a group.
  • The elements within a group have similar properties.
  • The elements in a group have similar electron configurations.
