  1. Noble Gas Notation A shorthand method of writing electron configuration

  2. Noble Gases •  group 18 elements • Noble gas configurationthe outer main energy level is fully occupied by 8 electrons

  3. Steps to Write a Noble Gas Notation • write down the symbol of the preceding noble gas (last column) • Draw brackets around the noble gas symbol like this [Ne] • write the electron configuration starting from there

  4. Practice • Write the noble gas notation for Ca • The preceding noble gas is Ar • Use the periodic table to find the next principal quantum number • [Ar] 4s2

  5. Additional Practice • Write the noble gas notation for Zr • The preceding noble gas is Kr • [Kr] 5s2 4d2 • Write the noble gas notation for Ni • The preceding noble gas is [Ar] • [Ar] 4s2 3d8
