On the other hand, arsenic is not malleable or ductile, is brittle and can be easily. On the one hand, arsenic is a solid at room temperature, has metallic luster, and is a good conductor of electricity, which are typical characteristics of metals. References: Los Alamos National Laboratory (2001), Crescent Chemical Company (2001), Lange's Handbook of Chemistry (1952), CRC Handbook of Chemistry & Physics (18th Ed.) Arsenic is classified as a metalloid because it has properties of both metals and nonmetals. Mercury is obtained from cinnabar by heating the cinnabar in air and condensing the vapor.Īppearance: heavy, silvery-white metal that is liquid at room temperature It is also malleable, which means that it. It is ductile, which means that it can be stretched out into wires or thin filaments. Sources: Mercury rarely occurs free in nature. Become a member to unlock this answer Create your account. Many of the salts and organic mercury compounds are important. These distinctions are quite arbitrary, as all elements have more or less metallic character - there are no 'true' metals or non-metals (we call the ones we. Mercury is used to make thermometers, diffusion pumps, barometers, mercury vapor lamps, mercury switches, pesticides, batteries, dental preparations, antifouling paints, pigments, and catalysts. Uses: Mercury is amalgamated with gold to facilitate the recovery of gold from its ores. The concentration, and thus the danger, increases at higher temperatures. When room temperature air (20☌) is saturated with mercury vapor, the concentration greatly exceeds the toxic limit. Mercury is readily absorbed across unbroken skin or though the respiratory or gatroinstentinal tract. Mercury and its compounds are highly poisonous. An electrical discharge will cause mercury to combine with the noble gases argon, krypton, neon, and xenon. Mercury readily forms alloys with other metals, called amalgams. It is a relatively poor conductor of heat, but a fair conductor of electricity. Mercury is one of the few elements that is liquid at ordinary room temperatures. Properties: Mercury has a melting point of -38.842☌, boiling point of 356.58☌, specific gravity of 13.546 (20☌), and a valence of 1 or 2. Word Origin: from the Planet Mercury Hg is the symbol for Hydrargyrum, which means liquid silver Mercury has been found in Egyptian tombs dating to 1500 B.C.Įlectron Configuration: 4f14 5d10 6s2

Mercury (Hydrargyrum) Atomic Number: 80ĭiscovery: Known to the ancient Hindus and Chinese. Mercury is metal and one out of the rest of the elements, it is a liquid at room temperature.
