Krypton (Kr) - Uses of Krypton & Chemical Properties of
Jul 25, 2018 · Krypton is a chemical element and a rare gas of the Group 18 with atomic number 18 and symbol Ar in the periodic table. This gas is almost three times heavier than the air. It is colourless, tasteless, monatomic and odourless. This gas is more plentiful in Earth’s atmosphere as its traces are present in minerals and meteorites.
Krypton is present in the air at about 1 ppm. The atmosphere of Mars contains a little (about 0.3 ppm) of krypton. It is characterised by its brilliant green and orange spectral lines. The spectral lines of krypton are easily produced and some are very sharp.

Feb 28, 2020 · The most stable oxidation state of the element is −1, in which bromine occurs naturally. But oxidation states of 0 (elemental bromine, Br 2 ), +1 (hypobromite, BrO − ), +3 (bromite, BrO −2 ), +5 (bromate, BrO −3 ), and +7 (perbromate, BrO −4) are also known. The first ionization energy of
Properties of Noble Gases. Noble gases are relatively non-reactive in nature – a property which can be attributed to their full or complete outer shell of valence electrons which gives them very little or absolutely no ability to indulge in chemical reactions.
Potassium Bromide (KBr)Structure, Physical and Chemical
Potassium Bromide (KBr)Structure, Physical and Chemical Properties He potassium bromide (KBr) is a haloide salt produced by a highly electropositive element, such as potassium (K), and highly electronegative, such as bromine (Br). The physical aspect is a white crystalline solid and is hygroscopic; that is, it absorbs water from the medium.
The physical properties of polyethylene are mainly determined by its crystallinity. Crystallisation can occur better when the degree of branching is lower. The branching accounts for the differences in physical properties between the different grades of polyethylene. Due to its lower degree of branching high density polyethylene is more rigid,
