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. The chemical symbol for Boron is B. According to the Einstein relationship (E=mc2), this binding energy is proportional to this mass difference and it is known as the mass defect. It is even less abundant than the so-called rare earths. Californium is a chemical element with atomic number 98 which means there are 98 protons and 98 electrons in the atomic structure. It occurs on Earth as the decay product of various heavier elements. The chemical symbol for Thorium is Th. The chemical symbol for Lithium is Li. Sodium is a soft, silvery-white, highly reactive metal. In nuclear industry boron is commonly used as a neutron absorber due to the high neutron cross-section of isotope 10B.

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. These elements, along with the chemically similar elements scandium and yttrium, are often collectively known as the rare earth elements. It is one of the least reactive chemical elements and is solid under standard conditions. The chemical symbol for Iridium is Ir. The classical description cannot be used to describe things on the atomic scale. The chemical symbol for Potassium is K. Potassium was first isolated from potash, the ashes of plants, from which its name derives. Curium is a hard, dense, silvery metal with a relatively high melting point and boiling point for an actinide. Iodine is the least abundant of the stable halogens, being the sixty-first most abundant element. The chemical symbol for Gold is Au. Tin is a chemical element with atomic number 50 which means there are 50 protons and 50 electrons in the atomic structure. The chemical symbol for Thallium is Tl. What is the volume of the earth in cubic centimeters if the radius r of the earth is 6.38 x 108cm? Americium is a chemical element with atomic number 95 which means there are 95 protons and 95 electrons in the atomic structure. Chromium is a steely-grey, lustrous, hard and brittle metal4 which takes a high polish, resists tarnishing, and has a high melting point. 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 Rhenium is Re. Units of measure have been defined for mass and energy on the atomic scale to make measurements more convenient to express. Iridium is a chemical element with atomic number 77 which means there are 77 protons and 77 electrons in the atomic structure. Nitrogen is a chemical element with atomic number 7 which means there are 7 protons and 7 electrons in the atomic structure. Manganese is a metal with important industrial metal alloy uses, particularly in stainless steels. 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’.

Assuming spherical shape, the uranium atom have volume of about 26.9 ×10−30 m3. Fermium is a member of the actinide series. The metal is found in the Earth’s crust in the pure, free elemental form (“native silver”), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Rhenium is a silvery-white, heavy, third-row transition metal in group 7 of the periodic table. The chemical symbol for Oxygen is O. Discoverer: Corson, Dale R. and Mackenzie, K. R.
