Question

how is an orbital different from the orbit described by bohr

Answer 1

Orbit is basically 2d and orbital is 3d.
Orbit is the concept of Bohr's atomic theory while orbital is the concept of the quntum theory.
In an atom only orbital exists because as per heisenberg's uncertainity principle it is impossible to define the exact trajectory
of electron and hence orbit cannot exist.
Orbital is basically the region where the probability of finding electron is max.. ie.

Answer 2

Neils Bohr's orbits describe the motion of electrons around a nucleus. Orbital is more generic and can refer to other types of orbits such as molecular orbits where an electron may orbit the whole molecule (more specifically covalent bonds) rather than confined to a single atom - i.e. what are known as 'bond electrons'.
I should also mention that a popular usage of the term 'The Orbital Electron' generally refers to the outer most electron(s) in an atom.

Answer 3

An \(\sf\color{red}{orbit}\) is a fixed path that an object takes (an electron in this case) and it can jump back and forth between these orbits (or "levels"). This is analogous to our planetary system where planets orbit the sun.

An \(\sf\color{red}{orbital}\) is statistical measure of the electron's whereabouts, referred to as the "probability density". Because electrons (as all particles) exhibit wave-like and particle-like behaviour, ("wave-particle duality") their behaviour is strange, this strays from the classical behaviour were used to with macroscopic objects. When trying to determine characteristics of these small objects, like the position of an electron, were limited to measuring possible outcomes, like "what is the probability of rolling a die and getting a 2?, and a specific orbital is one of those possible outcomes.
