Electron orbitals are regions around the nucleus of an atom where electrons with certain energy levels are most likely to be found.
Atomic Orbital: This refers to the region within an atom that can hold up to two electrons, with both having opposite spins.
Quantum Numbers: These are sets of numerical values that describe the characteristics of atomic orbitals and the electrons in those orbitals.
This is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals.
