Noble gases are a special group of elements found in Group 18 of the periodic table. They have some really interesting features:
Not Reactive: Noble gases don't easily mix with other elements. This is because their outer shell of electrons is full, which makes them very stable.
Weight Difference: Helium is the lightest noble gas, while radon is one of the heaviest. For example, helium's density is about 0.009 grams per liter, and radon's density is around 0.00973 grams per milliliter.
Everyday Uses: Neon is famous for being used in bright signs, and argon is often used in welding because it helps to protect the metal from reacting with air.
These cool characteristics make us want to learn more about atoms and how they interact!
