How do your write a noble gas configuration for atoms of an element? 40 points!

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. Put the atomic number of the noble gas beneath the symbol to let you know the number of electrons already represented. Take note of the row the noble gas is in on the periodic table.

Step 4: Continue your electron configuration using the row after the noble gas. For example, Krypton ends the 4th row so you would begin with 5. Always begin with the s subshell.

Step 5: Continue writing your electron configuration following the chart until you reach the correct number of electrons.

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
