Noble Gas Configuration - Lesson

What is the general rule for writing electron configurations using noble gas notation?

• Write the symbol of the noble gas that comes after the element, followed by the remaining electrons.

• Write the symbol of the noble gas that immediately precedes the element, enclosed in brackets, followed by the remaining electrons.

• Write the full electron configuration, then identify the noble gas portion.

• Write the symbol of any noble gas, followed by all the element's electrons.
