What is Orbital?
A mathematical function describing the wave-like behavior of an electron in an atom (atomic orbital) or molecule (molecular orbital). The square of the orbital function gives the probability density of finding the electron in a region of space. Types: s, p, d, f.

A mathematical function describing the wave-like behavior of an electron in an atom (atomic orbital) or molecule (molecular orbital). The square of the orbital function gives the probability density of finding the electron in a region of space. Types: s, p, d, f.
Orbitals explain: periodic trends in atomic properties, chemical bonding (overlap of orbitals forms bonds), spectroscopy (electronic transitions between orbitals), magnetism (unpaired electrons in half-filled orbitals), and reactivity (HOMO/LUMO in frontier MO theory). Orbital hybridisation explains…
No direct safety concern. Understanding orbital theory helps predict chemical reactivity and the hazard of excited state chemistry (UV-excited orbitals can react with DNA, causing mutations). Frontier orbital analysis guides understanding of why certain carcinogens react preferentially with DNA.
The formula or notation for Orbital is: ψ(r,θ,φ): quantum wavefunction squared gives probability density
