Explain the context and meanings of the terms "orbit" and "orbital", making a clear distinction between them.
Answer: Orbit is a term from the Bohr theory, and refers to an exact, circular path followed
by an electron. It has been superseded by the concept of an orbital, which arises from the Schrodinger equation. An orbital is a wave function, or, more loosely, a region of space close to the nucleus where an electron is likely to be found.
