Idea

A Bott element is an element in a periodic cohomology theory, multiplication by which is invertible.

Specifically for complex topological K-theory there is an element of degree 2 which induces Bott periodicity. This is where the term “Bott element” comes from. For details on this case see at fundamental product theorem in topological K-theory.
