Interpretation:
The differences between orbit and orbital are to be explained.
Concept introduction:
Bohr’s suggest that electrons are revolving around the nucleus in orbits and each orbit have a definite energy. According to modern wave picture of atom, orbital is the region within an atom where electrons are encloses and its finding probability is 90%.

Answer to Problem 22A
Electros are revolved in the circular orbits around the nucleus. An orbital is the region inside a atom where electrons are trapped.
Explanation of Solution
Orbit: Electrons are revolving around the nucleus in circular orbits and each orbit has a definite amount of energy. These orbits are lies at different distances from the nucleus of the atom.
Orbital: According to modern wave theory, orbital is the area inside an atom where the electrons finding probability is maximum.
In orbits, electrons are revolved around the nucleus while orbital is the region inside the atom where electrons are enclosed.
