Phosphorus, atomic structure C018 / 3696
Argon (Ar). Diagram of the nuclear composition, electron configuration, chemical data, and valence orbitals of an atom of argon-40 (atomic number: 18), the most common terrestrial isotope of this element. The nucleus consists of 18 protons (red) and 22 neutrons (orange). 18 electrons (white) occupy shells (rings); eight fill the outer (third) electron shell in what is a very stable configuration. The stability of an elements outer (valence) electrons determines its chemical and physical properties. Argon is a noble gas in group 18, period 3, and the p-block of the periodic table. An inert gas formed from the decay of potassium-40, it is used in fluorescent lighting and lasers

EDITORS COMMENTS
This print showcases the atomic structure of argon-40, the most abundant isotope of this element found on Earth. The image reveals a detailed diagram of the nuclear composition, electron configuration, and valence orbitals of an argon atom. At its core, 18 protons and 22 neutrons form the nucleus (depicted in red and orange respectively), while 18 electrons occupy various shells or rings around it (shown in white). Notably, eight electrons fill the outermost shell, creating a highly stable configuration. Argon belongs to group 18 and period 3 on the periodic table, making it a noble gas. It falls within the p-block category due to its electronic structure. Interestingly, this inert gas is formed through potassium-40 decay and finds applications in fluorescent lighting and lasers. The visual representation against a black background emphasizes key elements such as symbol illustrations, solid structures, wave functions, atomic weights (in pm), elemental properties like physical chemistry characteristics. Additionally highlighted are subatomic details including neutron numbers and proton numbers along with energy levels associated with different electron shells. Overall, this print provides insight into argon's unique atomic properties that contribute to its chemical behavior as well as physical attributes.
