Argon (Ar) is a noble gas found in Group 0 on the periodic table. It gets its name because of its chemical inertness and comes from the Greek root ‘Argo‚’ which means lazy. This is because Argon doesn’t react well with other elements. The atomic number of Argon is 18 making it a member of the helium group of elements which are also called noble‚ or inert‚ gasses and are non reactive. Its electronic configuration is: 1s2 2s2 2p6 3s2 3p6 The outermost shell‚ shell number three‚ has a completely
