Gold is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal. These have similar chemical properties, but palladium has the lowest melting point and is the least dense of them. Melting point
Neptunium is a chemical element with atomic number 93 which means there are 93 protons and 93 electrons in the atomic structure. It is obtained chiefly from the mineral cassiterite, which contains tin dioxide. In fact, you can't actually touch the metal itself since it spontaneously bursts into flames in the presence of air and reacts explosively with water. Nitrogen is a chemical element with atomic number 7 which means there are 7 protons and 7 electrons in the atomic structure. The chemical symbol for Platinum is Pt. The most stable isotope of berkelium - 247Bk - has an atomic mass of 247. Values are given for typical oxidation number and coordination. Osmium is a hard, brittle, bluish-white transition metal in the platinum group that is found as a trace element in alloys, mostly in platinum ores. Gold is thought to have been produced in supernova nucleosynthesis, from the collision of neutron stars. Now next week, an element that requires a magic touch - as long as you don't get too close. Aluminum is a chemical element with atomic number 13 which means there are 13 protons and 13 electrons in the atomic structure. Although the pure element has not yet been isolated, it is predicted to be a silvery metal that would easily oxidise in air at high temperatures and would be soluble in dilute mineral acids. The chemical symbol for Promethium is Pm. In some respects zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size. The chemical symbol for Zinc is Zn. Density of Berkelium is 14.78g/cm3. The chemical symbol for Francium is Fr. Discoverer: Scientists at Dubna, Russia (1964)/Albert Ghiorso et. Berkelium was discovered after americium, curium, plutonium, and neptunium and belongs to the transuranium and actinide series. The chemical symbol for Lutetium is Lu. Berkelium has twenty known isotopes with mass number ranging from 235 to 254 with no stable isotope. Protons:97. Platinum is used in catalytic converters, laboratory equipment, electrical contacts and electrodes, platinum resistance thermometers, dentistry equipment, and jewelry. Dysprosium is used for its high thermal neutron absorption cross-section in making control rods in nuclear reactors, for its high magnetic susceptibility in data storage applications. Atomic Symbol: Bk: Melting Point: 986 °C: Atomic Weight: 247: Boiling Point: 2627 °C: Electron Configuration: [Rn]7s 2 5f 9: Oxidation States: 2, 3, 4: History. These values were determined using several different methods. Its longest-lived isotopes, Bk-247 and Bk-248, have half-lives of 1,380 years and more than 9 years, respectively; the isotope produced in greatest quantity, Bk-249, has a half-life of 330 days. Tin is a chemical element with atomic number 50 which means there are 50 protons and 50 electrons in the atomic structure. Melting point. Atomic properties of berkelium. Curium is a hard, dense, silvery metal with a relatively high melting point and boiling point for an actinide. The chemical symbol for Boron is B. Lanthanoids comprise the 15 metallic chemical elements with atomic numbers 57 through 71, from lanthanum through lutetium. It is an extremely reactive element and a strong oxidising agent: among the elements, it has the highest electron affinity and the third-highest electronegativity, behind only oxygen and fluorine. The chemical symbol for Magnesium is Mg. Magnesium is a shiny gray solid which bears a close physical resemblance to the other five elements in the second column (group 2, or alkaline earth metals) of the periodic table: all group 2 elements have the same electron configuration in the outer electron shell and a similar crystal structure. The chemical symbol for Krypton is Kr. Like other actinides, berkelium accumulates in skeletal tissue and is therefore highly toxic to humans. Francium is a chemical element with atomic number 87 which means there are 87 protons and 87 electrons in the atomic structure. Less than a gram of berkelium is made each year. The university and the city of Berkeley were in turn named after the Anglo-Irish philosopher, Bishop George 'B. Atomic Number of Berkelium is 97..
