Mercury(II) Trifluoromethanesulfonate

See more Mercury products. Mercury (atomic symbol: Hg, atomic number: 80) is a Block D, Group 12, Period 6 element with an atomic weight of 200.59. The number of electrons in each of mercury's shells is 2, 8, 18,32, 18, 2 and its electron configuration is [Xe] 4f¹⁴ 5d¹⁰ 6s². The mercury atom has a radius of 151 pm and a Van der Waals radius of 209 pm. It is named after the planet Mercury and often referred to as "quicksilver" due to its appearance as a silvery liquid. Mercury has low melting and boiling points. It is a poor conductor of heat, but a fair conductor of electricity. Mercury is found both as a free element and in cinnabar, corderoite, and livingstonite ores.

See more Sulfur products. Sulfur (or Sulphur) (atomic symbol: S, atomic number: 16) is a Block P, Group 16, Period 3 element with an atomic radius of 32.066. The number of electrons in each of Sulfur's shells is 2, 8, 6 and its electron configuration is [Ne] 3s² 3p⁴. In its elemental form, sulfur has a light yellow appearance. The sulfur atom has a covalent radius of 105 pm and a Van der Waals radius of 180 pm. In nature, sulfur can be found in hot springs, meteorites, volcanoes, and as galena, gypsum, and epsom salts. Sulfur has been known since ancient times but was not accepted as an element until 1777, when Antoine Lavoisier helped to convince the scientific community that it was an element and not a compound.

Fluorine is a Block P, Group 17, Period 2 element. Its electron configuration is [He]2s²2p⁵. The fluorine atom has a covalent radius of 64 pm and its Van der Waals radius is 135 pm. In its elemental form, CAS 7782-41-4, fluorine gas has a pale yellow appearance. Fluorine was discovered by André-Marie Ampère in 1810. It was first isolated by Henri Moissan in 1886.
