The periodic table contains eleven elements which are in the gas phase under standard conditions, namely hydrogen, nitrogen, oxygen, fluorine, chlorine, and the six noble gases.Of these elements, chlorine has the highest boiling point of -34.0 C (239.1 K, -29.3 F). Only about 5×10−8% of all matter in the universe is europium. The chemical symbol for Tellurium is Te. The chemical symbol for Titanium is Ti. Bromine is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured gas. Aluminium is a silvery-white, soft, nonmagnetic, ductile metal in the boron group. Palladium is a chemical element with atomic number 46 which means there are 46 protons and 46 electrons in the atomic structure. F Chlorine is a member of Group 7, the halogens, which consists of fluorine, chlorine, bromine, iodine and astatine. The chemical symbol for Silicon is Si. Cerium is a soft, ductile and silvery-white metal that tarnishes when exposed to air, and it is soft enough to be cut with a knife. Uranium is weakly radioactive because all isotopes of uranium are unstable, with half-lives varying between 159,200 years and 4.5 billion years. Yttrium is a chemical element with atomic number 39 which means there are 39 protons and 39 electrons in the atomic structure. It is the fourth most common element in the Earth’s crust. Silicon is a chemical element with atomic number 14 which means there are 14 protons and 14 electrons in the atomic structure. Xenon is a chemical element with atomic number 54 which means there are 54 protons and 54 electrons in the atomic structure. Discoverer: Marinsky, Jacob A. and Coryell, Charles D. and Glendenin, Lawerence. When considered as the temperature of the reverse change from vapor to liquid, it is referred to as the condensation point. Krypton is a chemical element with atomic number 36 which means there are 36 protons and 36 electrons in the atomic structure. Argon is mostly used as an inert shielding gas in welding and other high-temperature industrial processes where ordinarily unreactive substances become reactive; for example, an argon atmosphere is used in graphite electric furnaces to prevent the graphite from burning. Curium is a hard, dense, silvery metal with a relatively high melting point and boiling point for an actinide. Under standard conditions, it is the lightest metal and the lightest solid element. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass. Like the other metals of the platinum group, ruthenium is inert to most other chemicals. The chemical symbol for Chromium is Cr. The chemical symbol for Indium is In. Pure germanium is a semiconductor with an appearance similar to elemental silicon. Because of its high chemical reactivity, barium is never found in nature as a free element. On the other hand, chlorine dioxide is an inorganic compound having the chemical formula ClO 2. Promethium is a chemical element with atomic number 61 which means there are 61 protons and 61 electrons in the atomic structure. The chemical symbol for Rhenium is Re. Erbium is a silvery-white solid metal when artificially isolated, natural erbium is always found in chemical combination with other elements. Cerium is the second element in the lanthanide series. Atomic Weight: 35.4527. The chemical symbol for Samarium is Sm. Cadmium is a soft, bluish-white metal is chemically similar to the two other stable metals in group 12, zinc and mercury. 113Cd has specific absorption cross-section. Liquid nitrogen (made by distilling liquid air) boils at 77.4 kelvins (−195.8°C) and is used as a coolant. Chlorine is intermediate in reactivity between fluorine and bromine, and is one of the most reactive elements. The chemical symbol for Tungsten is W. Tungsten is a rare metal found naturally on Earth almost exclusively in chemical compounds. The chemical symbol for Manganese is Mn.
