Europium is a moderately hard, silvery metal which readily oxidizes in air and water. That was Matt Wilkinson who will be here with the story of Lithium on next week's Chemistry in its Element, I do hope you can join us. This is because it is able to form a huge variety of chains of different lengths. The chemical symbol for Lithium is Li. The melting point also defines a condition in which the solid and liquid can exist in equilibrium. Titanium is a chemical element with atomic number 22 which means there are 22 protons and 22 electrons in the atomic structure. Its abundance in rocky planets like Earth is due to its abundant production by fusion in high-mass stars. Elemental sulfur is a bright yellow crystalline solid at room temperature. Palladium, platinum, rhodium, ruthenium, iridium and osmium form a group of elements referred to as the platinum group metals (PGMs). Neon is a colorless, odorless, inert monatomic gas under standard conditions, with about two-thirds the density of air. Covalent radiusHalf of the distance between two atoms within a single covalent bond. The RSC has been granted the sole and exclusive right and licence to produce, publish and further license the Images. Platinum is used in catalytic converters, laboratory equipment, electrical contacts and electrodes, platinum resistance thermometers, dentistry equipment, and jewelry. The chemical symbol for Lanthanum is La. Unfortunately, diamond also has a dark side - the greed that diamond induces leads to the trade of so-called 'conflict diamonds' that support and fund civil wars. It is a noble metal and a member of the platinum group. The arrangements of electrons above the last (closed shell) noble gas. The oxygen is released to the atmosphere, fresh water and seas, and the hydrogen joins with carbon dioxide to produce carbohydrates. Nobelium is the tenth transuranic element and is the penultimate member of the actinide series. Caesium is a soft, silvery-gold alkali metal with a melting point of 28.5 °C, which makes it one of only five elemental metals that are liquid at or near room temperature. By mass, oxygen is the third-most abundant element in the universe, after hydrogen and helium. At the melting point the two phases of a substance, liquid and vapor, have identical free energies and therefore are equally likely to exist. In general, melting is a phase change of a substance from the solid to the liquid phase. The chemical symbol for Bismuth is Bi. Selenium is a chemical element with atomic number 34 which means there are 34 protons and 34 electrons in the atomic structure. Oxygen is a colourless, odourless reactive gas, the chemical element of atomic number 8 and the life-supporting component of the air. The atomic number of each element increases by one, reading from left to right. It seems that every few years a new form of carbon comes into fashion - A few years ago carbon nanotubes were the new black (or should I say 'the new bucky-ball') - but graphene is oh-so-now! Rubidium is a chemical element with atomic number 37 which means there are 37 protons and 37 electrons in the atomic structure. It is the hardest material known to man and more or less inert - able to withstand the strongest and most corrosive of acids. The chemical symbol for Carbon is C. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. Tellurium is chemically related to selenium and sulfur. The atomic number of each element increases by one, reading from left to right. Nearly all technetium is produced synthetically, and only minute amounts are found in the Earth’s crust. The allotropes of carbon include graphite, one of the softest known substances, and diamond, the hardest naturally occurring substance. It is the fourth most common element in the Earth’s crust. The chemical symbol for Neon is Ne. Actinium gave the name to the actinide series, a group of 15 similar elements between actinium and lawrencium in the periodic table. Values are given for typical oxidation number and coordination. Density (g cm −3) Osmium is a chemical element with atomic number 76 which means there are 76 protons and 76 electrons in the atomic structure. The ninth member of the lanthanide series, terbium is a fairly electropositive metal that reacts with water, evolving hydrogen gas. This is approximately the sum of the number of protons and neutrons in the nucleus. The chemical symbol for Radon is Rn. Praseodymium is a soft, silvery, malleable and ductile metal, valued for its magnetic, electrical, chemical, and optical properties. Data for this section been provided by the British Geological Survey. Pierre-Joseph Macquer and Godefroy de Villetaneuse repeated the experiment in 1771. The temperature at which the liquid–gas phase change occurs. At 0.099%, phosphorus is the most abundant pnictogen in the Earth’s crust. Major advantage of lead shield is in its compactness due to its higher density. Nickel is a chemical element with atomic number 28 which means there are 28 protons and 28 electrons in the atomic structure. Text © The Royal Society of Chemistry 1999-2011 The most probable fission fragment masses are around mass 95 (Krypton) and 137 (Barium). Francium is a highly radioactive metal that decays into astatine, radium, and radon. The melting point is the temperature at which the disruptive vibrations of the particles of the solid overcome the attractive forces operating within the solid. The chemical symbol for Californium is Cf. Carbon dioxide, in its solid form, is commonly known as dry ice. Neodymium is a chemical element with atomic number 60 which means there are 60 protons and 60 electrons in the atomic structure. A measure of how difficult it is to deform a material. Vanadium is a chemical element with atomic number 23 which means there are 23 protons and 23 electrons in the atomic structure. The chemical symbol for Nickel is Ni. Bromine is a chemical element with atomic number 35 which means there are 35 protons and 35 electrons in the atomic structure. Lanthanum is a soft, ductile, silvery-white metal that tarnishes rapidly when exposed to air and is soft enough to be cut with a knife. The chemical symbol for Barium is Ba. It is found in respirators and kitchen extractor hoods. For example, sodium chloride  (NaCl) is an ionic compound that consists of a multitude of strong ionic bonds.
