An element cannot be broken down into other substances by chemical or physical means. But you can still split a sample of an element into smaller pieces. For example, a piece of aluminum foil can be cut in half and then in half again, and all of the pieces will still be aluminum. What do you think will eventually happen if you could continue dividing that piece of aluminum foil You will reach the smallest possible piece of the aluminum.
You will divide the aluminum into two smaller elements.
You will continue dividing the aluminum forever into smaller and smaller pieces.
You will reach a point at which there is no matter left.

You will reach the smallest possible piece of the aluminum.

Explanation:

You will not be able to physically separate the aluminum into two smaller elements; aluminum is already a pure elemental substance. It will not divide forever, at some point it will be as small as you can possibly make it. However, you won't be able to erase the matter completely -- it will just become very very small!
