Element
Element explained in an easy to understand way:
Imagine you have a jigsaw puzzle where every piece is exactly the same, making it impossible to break down into more basic parts. This is similar to an element, which is a substance made of one type of atom that cannot be broken down chemically into simpler substances. Just like the puzzle pieces that are all identical and form a complete image on their own, an element consists entirely of one kind of atom, which defines its unique properties and cannot be reduced further.
