Significant concentrations of boron occur on the Earth in compounds known as the borate minerals. Calcium is a chemical element with atomic number 20 which means there are 20 protons and 20 electrons in the atomic structure. Atomic radius is defined as the distance from the center of the nucleus of an atom to the outermost shell of electrons. Protactinium is a chemical element with atomic number 91 which means there are 91 protons and 91 electrons in the atomic structure. But this “huge” space is occupied primarily by electrons, because the nucleus occupies only about 1721×10−45 m3 of space. The chemical symbol for Barium is Ba. Antimony is a lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite. Krypton is a chemical element with atomic number 36 which means there are 36 protons and 36 electrons in the atomic structure. Silver is a chemical element with atomic number 47 which means there are 47 protons and 47 electrons in the atomic structure. Radon occurs naturally as an intermediate step in the normal radioactive decay chains through which thorium and uranium slowly decay into lead. Nobelium is the tenth transuranic element and is the penultimate member of the actinide series. The chemical symbol for Rhodium is Rh. The chemical symbol for Titanium is Ti. Ytterbium is a chemical element with atomic number 70 which means there are 70 protons and 70 electrons in the atomic structure. Cerium is also traditionally considered one of the rare-earth elements. In nuclear industry boron is commonly used as a neutron absorber due to the high neutron cross-section of isotope 10B. Rhenium is a chemical element with atomic number 75 which means there are 75 protons and 75 electrons in the atomic structure. Since the boundary is not a well-defined physical entity, there are various non-equivalent definitions of atomic radius. Atomic number of Calcium (Ca) = 20 Atomic number of Cobalt (Co) = 27 and Atomic number of Nickel (Ni) = 28 Clearly, Nickel (Ni) ha s the largest atomic radius. Erbium is a silvery-white solid metal when artificially isolated, natural erbium is always found in chemical combination with other elements. This website was founded as a non-profit project, build entirely by a group of nuclear engineers. Thorium metal is silvery and tarnishes black when exposed to air, forming the dioxide. Iodine is the least abundant of the stable halogens, being the sixty-first most abundant element. Silicon is a chemical element with atomic number 14 which means there are 14 protons and 14 electrons in the atomic structure. The first alloy used on a large scale was bronze, made of tin and copper, from as early as 3000 BC.

It readily forms hard, stable carbides in alloys, and for this reason most of world production of the element (about 80%) is used in steel alloys, including high-strength alloys and superalloys. Consequently, the smallest atom is helium with a radius of 32 pm, while one of the largest is caesium at 225 pm. Liquid nitrogen (made by distilling liquid air) boils at 77.4 kelvins (−195.8°C) and is used as a coolant. Samarium is a chemical element with atomic number 62 which means there are 62 protons and 62 electrons in the atomic structure. Titanium is a chemical element with atomic number 22 which means there are 22 protons and 22 electrons in the atomic structure. Fermium is a member of the actinide series. Silver is a soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The chemical symbol for Yttrium is Y. Yttrium is a silvery-metallic transition metal chemically similar to the lanthanides and has often been classified as a “rare-earth element”. Nitrogen. The ionic radius is half the distance between two gas atoms that are just touching each other. Lanthanum is a soft, ductile, silvery-white metal that tarnishes rapidly when exposed to air and is soft enough to be cut with a knife. In nuclear industry, especially natural and artificial samarium 149 has an important impact on the operation of a nuclear reactor. Chemically, indium is similar to gallium and thallium. It is obtained chiefly from the mineral cassiterite, which contains tin dioxide. 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.
