One may also ask, how do you shorthand noble gases? Follow the steps below to write short cut version of electron configurations.

Step 1: Find the element on the periodic table. Step 2: Go back to the last noble gas that was passed (atomic number). Step 3: Write the symbol of the noble gas in brackets to start your electron configuration.

In this regard, which elements have a noble gas configuration?

This provides the basis for a shorthand notation for electron configurations called the noble gas configuration. The elements that are found in the last column of the periodic table are an important group of elements that are called the noble gases. They are helium, neon, argon, krypton, xenon, and radon.

How many electrons does BR have?
