Noble Gas Notation
A shorthand method of writing electron configuration
Noble Gases
group 18 elementsNoble gas configurationthe outer main
energy level is fully occupied by 8 electrons
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
Practice
Write the noble gas notation for CaThe preceding noble gas is ArUse the periodic table to find the next
principal quantum number[Ar] 4s2
Additional Practice
Write the noble gas notation for ZrThe preceding noble gas is Kr[Kr] 5s2 4d2
Write the noble gas notation for NiThe preceding noble gas is [Ar][Ar] 4s2 3d8
