What new atom model did the study of quantum mechanics lead to?

The study of quantum mechanics led to the development of the quantum mechanical model of the atom, which replaced the earlier Bohr model. This model describes electrons as existing in probabilistic clouds, known as orbitals, rather than fixed orbits around the nucleus. It incorporates principles such as wave-particle duality and uncertainty, fundamentally changing our understanding of atomic structure and behavior. As a result, this model emphasizes the probabilistic nature of electron locations and energies within an atom.
