Platinum is used in catalytic converters, laboratory equipment, electrical contacts and electrodes, platinum resistance thermometers, dentistry equipment, and jewelry. Atomic Mass. Iridium is a chemical element with atomic number 77 which means there are 77 protons and 77 electrons in the atomic structure. It is occasionally found in native form as elemental crystals. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins. It is by mass the most common element on Earth, forming much of Earth’s outer and inner core. Cerium is a chemical element with atomic number 58 which means there are 58 protons and 58 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. It is the heaviest element that can be formed by neutron bombardment of lighter elements, and hence the last element that can be prepared in macroscopic quantities. Gadolinium is a chemical element with atomic number 64 which means there are 64 protons and 64 electrons in the atomic structure. It occurs on Earth as the decay product of various heavier elements. Its abundance in rocky planets like Earth is due to its abundant production by fusion in high-mass stars. Magnesium (12 Mg) naturally occurs in three stable isotopes, 24 Mg, 25 Mg, and 26 Mg. The chemical symbol for Vanadium is V. Vanadium is a hard, silvery grey, ductile, and malleable transition metal. Neon is a chemical element with atomic number 10 which means there are 10 protons and 10 electrons in the atomic structure. Since magnesium is very highly reactive, it canât be found freely in nature, but it can be obtained from a number of natural sources, manly such minerals as dolomites, magnesites, etc. The chemical symbol for Silicon is Si. The chemical symbol for Dysprosium is Dy. Magnesium is an element that is essential for human nutrition.
