The first theory explaining mechanism of melting in the bulk was proposed by Lindemann, who used vibration of atoms in the crystal to explain the melting transition. Curium is a hard, dense, silvery metal with a relatively high melting point and boiling point for an actinide. Though hydrogen bonds are the strongest of the intermolecular forces, the strength of hydrogen bonds is much less than that of ionic bonds. Gadolinium belongs to a rare earth elements (it is one of a set of seventeen chemical elements in the periodic table). Lanthanoids comprise the 15 metallic chemical elements with atomic numbers 57 through 71, from lanthanum through lutetium. Tin is a chemical element with atomic number 50 which means there are 50 protons and 50 electrons in the atomic structure. Hydrogen is a chemical element with atomic number 1 which means there are 1 protons and 1 electrons in the atomic structure.

The chemical symbol for Californium is Cf. The chemical symbol for Titanium is Ti. The chemical symbol for Cobalt is Co. Cobalt is found in the Earth’s crust only in chemically combined form, save for small deposits found in alloys of natural meteoric iron. Barium is the fifth element in group 2 and is a soft, silvery alkaline earth metal. The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal. The chemical symbol for Francium is Fr. Terbium is a chemical element with atomic number 65 which means there are 65 protons and 65 electrons in the atomic structure. Several references indicate platinum can not be enameled because it has a terrific expansion. Neodymium is not found naturally in metallic form or unmixed with other lanthanides, and it is usually refined for general use. And metal with lower force of attraction has lower melting point temperatures. Discoverer: Marinsky, Jacob A. and Coryell, Charles D. and Glendenin, Lawerence. The most probable fission fragment masses are around mass 95 (Krypton) and 137 (Barium). The chemical properties of this silvery gray, crystalline transition metal are intermediate between rhenium and manganese. Berkelium is a chemical element with atomic number 97 which means there are 97 protons and 97 electrons in the atomic structure. The chemical symbol for Einsteinium is Es. Neodymium is a soft silvery metal that tarnishes in air. Hafnium is a lustrous, silvery gray, tetravalent transition metal, hafnium chemically resembles zirconium and is found in many zirconium minerals.

Like all elements with atomic number over 100, lawrencium can only be produced in particle accelerators by bombarding lighter elements with charged particles. The melting point of a substance depends on pressure and is usually specified at standard pressure. Francium is an alkali metal, that has one valence electron. Helium is a chemical element with atomic number 2 which means there are 2 protons and 2 electrons in the atomic structure. The temperature at which vaporization (boiling) starts to occur for a given pressure is called the saturation temperature or boiling point. Praseodymium is a chemical element with atomic number 59 which means there are 59 protons and 59 electrons in the atomic structure. Berkelium: Value given for alpha form.

Carbon is one of the few elements known since antiquity. The chemical symbol for Radon is Rn. Uranium is a silvery-white metal in the actinide series of the periodic table. The atoms in a solid are tightly bound to each other, either in a regular geometric lattice (crystalline solids, which include metals and ordinary ice) or irregularly (an amorphous solid such as common window glass), and are typically low in energy. Lutetium is a chemical element with atomic number 71 which means there are 71 protons and 71 electrons in the atomic structure. Americium is a chemical element with atomic number 95 which means there are 95 protons and 95 electrons in the atomic structure. Note that, these points are associated with the standard atmospheric pressure. Bismuth is a chemical element with atomic number 83 which means there are 83 protons and 83 electrons in the atomic structure. At 0.099%, phosphorus is the most abundant pnictogen in the Earth’s crust. The chemical symbol for Lead is Pb. Platinum is resistant to corrosion when it comes into contact with air. Thorium is a naturally-occurring element and it is estimated to be about three times more abundant than uranium. The chemical symbol for Erbium is Er. The chemical symbol for Arsenic is As. The commercial use of beryllium requires the use of appropriate dust control equipment and industrial controls at all times because of the toxicity of inhaled beryllium-containing dusts that can cause a chronic life-threatening allergic disease in some people called berylliosis. Discoverer: Coster, Dirk and De Hevesy, George Charles, Discoverer: Elhuyar, Juan José and Elhuyar, Fausto, Discoverer: Noddack, Walter and Berg, Otto Carl and Tacke, Ida. Impurities.
