Atomic Structure Definition, Types, Examples & Uses

Atomic Structure

Subject: Chemistry

Book: General Chemistry

Atomic structure deals with the internal organization of an atom, including protons, neutrons, and electrons. Protons and neutrons form the nucleus, while electrons reside in orbitals around the nucleus. Quantum mechanics describes electron behavior, suggesting probability regions rather than fixed paths. Key concepts include atomic orbitals (s, p, d, f), quantum numbers, and energy levels. Understanding atomic structure is fundamental for explaining bonding, reactivity, and spectra of elements and molecules.
