The video explains that reactivity is a relative property, as even the least reactive elements, like noble gases, can undergo reactions. It highlights that noble gases, though least reactive, can form compounds under certain conditions, such as xenon tetrafluoride.

What does it mean when we say reactivity is a relative property?

• It means all elements react the same way.

• It means some elements never react.

• It means even the least reactive elements can undergo reactions.

• It means reactivity is not important in chemistry.

Which group of elements is known for being the least reactive?

• Halogens
