We all know about atomic orbitals and their 3D structure. But the structure in theoretical. What does these orbital really looks like
Atomic orbitals are just the solution of Schrodinger's wave equation. They help us to understand better the behaviour of electrons. Electrons behave more like waves and atomic orbitals can be thought of as places where the probability of finding those electrons is maximum. In reality, there is no such place as an atomic orbital.
