what is the region around the atomic nucleus where the electron is mostly found?

The region around the atomic nucleus where an electron is mostly found is called an orbital , often described as part of the atom’s electron cloud.

In modern atomic theory, an orbital is a three-dimensional region in space where there is a high probability of finding an electron at any given time, rather than a fixed circular path. These orbitals together form the electron cloud or shells around the nucleus, which helps explain how atoms bond and react in chemistry.
