Why are the radioactive elements considered elements if they eventually decay into lead?

If the definition of an element is a chemical substance that cannot be broken down into other substances, then aren’t the radioactive elements just extra-spicy lead?

That’s not the definition of an element. There are in fact, a LOT of particles smaller than elemental atoms once you start breaking things down.

An element is a type of atom (protons+neutrons bound together, orbited by electrons). The element of an atom is defined by the number of protons in its nucleus.
