Oxygen is a Group 16 element. While about one fifth of the atmosphere is oxygen gas, the atmosphere of Mars contains only about 0.15% oxygen. Oxygen is the third most abundant element found in the sun, and it plays a part in the carbon-nitrogen cycle, one process responsible for stellar energy production. Oxygen in excited states is responsible ...

Chlorine is a greenish yellow gas which combines directly with nearly all elements. Chlorine is a respiratory irritant. The gas irritates the mucous membranes and the liquid burns the skin. As little as 3.5 ppm can be detected as an odour, and 1000 ppm is likely to be fatal after a few deep breaths. It was used as a war gas in 1915.

Neon: description. Neon is a very inert element. Neon forms an unstable hydrate. In a vacuum discharge tube, neon glows reddish orange.

Finely divided metals, glass, ceramics, carbon, and even water burn in fluorine with a bright flame.

The periodic table is a masterpiece of organised chemical information and the evolution of chemistry's periodic table into the current form is an astonishing achievement. The International Union of Pure and Applied Chemistry (IUPAC) confirmed the names of elements 113, 115, 117, and 118 as:

Block in periodic table; Boiling point; Bond enthalpies; Bond length in element; Bulk modulus; CAS Registry ID; Classification; Colour; Covalent radii; Critical temperature; …
