Noble gases are a special group of elements found in Group 0 of the Periodic Table.

These gases are called "inert" because they don't usually react with other elements.

This is mainly because they have a full outer shell of electrons, which makes them very stable.

For example:

• Helium (He) has 2 electrons.
• Neon (Ne) has 10 electrons.
• Argon (Ar) has 18 electrons.

Because of this stability, they don't need to gain, lose, or share electrons with other elements.

Here are some examples of what these gases are used for:

• Helium: You might see it in balloons or in MRI machines to help keep them cool.
• Neon: This gas is well-known for its bright lights, like the ones you see in signs.
• Argon: It's often used in light bulbs to keep other gases from reacting inside them.

The fact that noble gases hardly react with anything makes them special and important for many uses!
