The chemical symbol for Chlorine is Cl. The bulk properties of astatine are not known with any certainty. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass. The chemical symbol for Molybdenum is Mo. Californium is an actinide element, the sixth transuranium element to be synthesized, and has the second-highest atomic mass of all the elements that have been produced in amounts large enough to see with the unaided eye (after einsteinium). The chemical symbol for Holmium is Ho. The chemical symbol for Iridium is Ir. Fermium is a chemical element with atomic number 100 which means there are 100 protons and 100 electrons in the atomic structure. In nuclear industry cadmium is commonly used as a thermal neutron absorber due to very high neutron absorption cross-section of 113Cd.    Alkaline Earth Metals The chemical symbol for Erbium is Er. As the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine. Naturally occurring potassium is composed of three isotopes, of which 40K is radioactive. For 12 C the atomic mass is exactly 12u, since the atomic mass unit is defined from it. The nucleus is composed of protons and neutrons. The chemical symbol for Lithium is Li. Since the density (ρ) of a substance is the total mass (m) of that substance divided by the total volume (V) occupied by that substance, it is obvious, the density of a substance strongly depends on its atomic mass and also on the atomic number density (N; atoms/cm3). The chemical symbol for Iron is Fe. A colorless, odorless, tasteless noble gas, krypton occurs in trace amounts in the atmosphere and is often used with other rare gases in fluorescent lamps. The chemical symbol for Fermium is Fm. The chemical symbol for Neodymium is Nd. Do you need to know the weight of some molecules? Thulium is an easily workable metal with a bright silvery-gray luster. The name xenon for this gas comes from the Greek word ξένον [xenon], neuter singular form of ξένος [xenos], meaning ‘foreign(er)’, ‘strange(r)’, or ‘guest’. Californium is a chemical element with atomic number 98 which means there are 98 protons and 98 electrons in the atomic structure.    Metalloids Curium is a chemical element with atomic number 96 which means there are 96 protons and 96 electrons in the atomic structure. The chemical symbol for Zinc is Zn. Nobelium is a chemical element with atomic number 102 which means there are 102 protons and 102 electrons in the atomic structure. Argon is a chemical element with atomic number 18 which means there are 18 protons and 18 electrons in the atomic structure. Major advantage of lead shield is in its compactness due to its higher density. The chemical symbol for Silicon is Si. Curium is a hard, dense, silvery metal with a relatively high melting point and boiling point for an actinide. The chemical symbol for Ruthenium is Ru. Gold is thought to have been produced in supernova nucleosynthesis, from the collision of neutron stars. It occurs on Earth as the decay product of various heavier elements. Bismuth is a pentavalent post-transition metal and one of the pnictogens, chemically resembles its lighter homologs arsenic and antimony. Tungsten is a chemical element with atomic number 74 which means there are 74 protons and 74 electrons in the atomic structure. It occurs on Earth as the decay product of various heavier elements. This is a list of chemical elements, sorted by atomic mass (or most stable isotope) and color coded according to type of element.Each element's atomic number, name, element symbol, and group and period numbers on the periodic table are given. Thulium is the thirteenth and third-last element in the lanthanide series. Copper is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. Tungsten is an intrinsically brittle and hard material, making it difficult to work. Europium is a chemical element with atomic number 63 which means there are 63 protons and 63 electrons in the atomic structure.
