These condensers use tubes that are usually made of stainless steel, copper alloys, or titanium depending on several selection criteria (such as thermal conductivity or corrosion resistance). Because of its closed-shell electron configuration, its density and melting and boiling points differ significantly from those of most other lanthanides.

A colorless, odorless, tasteless noble gas, krypton occurs in trace amounts in the atmosphere and is often used with other rare gases in fluorescent lamps. Uranium is weakly radioactive because all isotopes of uranium are unstable, with half-lives varying between 159,200 years and 4.5 billion years. All of its isotopes are radioactive.

[53] After about 1985, all new chloralkali production facilities that were built in the United States used membrane cell or diaphragm cell technologies to produce chlorine. A 2001 study measured mercury levels in 12 indoor sites chosen to represent a cross-section of building types, locations and ages in the New York area. Promethium is one of only two such elements that are followed in the periodic table by elements with stable forms. Mercury is commonly known as quicksilver and was formerly named hydrargyrum.
