Answer 1

• Noble gases, also known as inert gases are the elements that belong to group 18 of the modern periodic table.
• These elements exist in the gaseous phase.
• They are known to possess extremely low chemical reactivity because their valency is zero.
• The combining capacity of an element is called its valency.
• Hence, it is also known as the inert gas.
• For example, helium (He), neon (Ne), argon (Ar), etc.

Thus, noble gases are also known as inert gases.
