Density (g cm −3) Density is the mass of a substance that would fill 1 cm 3 at room temperature. Helium is a chemical element with atomic number 2 which means there are 2 protons and 2 electrons in the atomic structure. Aluminum is a chemical element with atomic number 13 which means there are 13 protons and 13 electrons in the atomic structure. Therefore, there are various non-equivalent definitions of atomic radius. The name xenon for this gas comes from the Greek word Î¾ÎÎ½Î¿Î½ [xenon], neuter singular form of Î¾ÎÎ½Î¿Ï [xenos], meaning âforeign(er)â, âstrange(r)â, or âguestâ. Bromine is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured gas. Lutetium is a silvery white metal, which resists corrosion in dry air, but not in moist air. Berkelium is a member of the actinide and transuranium element series. Therefore, the effective nuclear charge towards the outermost electrons increases, drawing the outermost electrons closer. Thorium is a naturally-occurring element and it is estimated to be about three times more abundant than uranium.

Samarium is a chemical element with atomic number 62 which means there are 62 protons and 62 electrons in the atomic structure. Bismuth is a chemical element with atomic number 83 which means there are 83 protons and 83 electrons in the atomic structure. Neon is a chemical element with atomic number 10 which means there are 10 protons and 10 electrons in the atomic structure. The chemical symbol for Carbon is C. It is nonmetallic and tetravalentâmaking four electrons available to form covalent chemical bonds.
Being a typical member of the lanthanide series, europium usually assumes the oxidation state +3. The chemical symbol for Fermium is Fm. It is by mass the most common element on Earth, forming much of Earthâs outer and inner core. Lead is widely used as a gamma shield. The chemical symbol for Europium is Eu. Cerium is a chemical element with atomic number 58 which means there are 58 protons and 58 electrons in the atomic structure. It is a member of the chalcogen group on the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds.
Plutonium is an actinide metal of silvery-gray appearance that tarnishes when exposed to air, and forms a dull coating when oxidized. Tellurium is chemically related to selenium and sulfur. Consequently, the smallest atom is helium with a radius of 32 pm, while one of the largest is caesium at 225 pm. Lawrencium is the final member of the actinide series. Mass was no longer considered unchangeable in the closed system. Copper is a chemical element with atomic number 29 which means there are 29 protons and 29 electrons in the atomic structure.
