In the periodic table, potassium is one of the alkali metals. Sodium is a soft, silvery-white, highly reactive metal.
Natural boron consists primarily of two stable isotopes, 11B (80.1%) and 10B (19.9%). Significant concentrations of boron occur on the Earth in compounds known as the borate minerals. ChromiumÂ is a chemical element withÂ atomic numberÂ 24Â which means there are 24 protons and 24 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.The chemical symbol for Silver is Ag.
TerbiumÂ is a chemical element withÂ atomic numberÂ 65Â which means there are 65 protons and 65 electrons in the atomic structure. When it is ionized, the electron is removed from the outermost shell, which is the 5s orbital.
HafniumÂ is a chemical element withÂ atomic numberÂ 72Â which means there are 72 protons and 72 electrons in the atomic structure. The element is much more stable and has a lower energy when the 4d orbital is filled, so one electron is placed there, rather than in the 5s orbital. TheÂ chemical symbolÂ for Praseodymium isÂ Pr. Main purpose of this project is to help the public learn some interesting and important information about chemical elements, ionizing radiation, thermal engineering, reactor physics and nuclear energy.

CalciumÂ is a chemical element withÂ atomic numberÂ 20Â which means there are 20 protons and 20 electrons in the atomic structure. TheÂ chemical symbolÂ for Platinum isÂ Pt.
TheÂ chemical symbolÂ for Sulfur isÂ S. Sulfur is abundant, multivalent, and nonmetallic. Cerium is a soft, ductile and silvery-white metal that tarnishes when exposed to air, and it is soft enough to be cut with a knife. Thulium is the thirteenth and third-last element in the lanthanide series.
Americium is a transuranic member of the actinide series, in the periodic table located under the lanthanide element europium, and thus by analogy was named after the Americas.
What is the electron configuration of copper? Silver is the best reflector as compared to all other metals.
Antimony is a lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite.
Like all elements with atomic number over 100, nobelium can only be produced in particle accelerators by bombarding lighter elements with charged particles.
Like all elements with atomic number over 100, lawrencium can only be produced in particle accelerators by bombarding lighter elements with charged particles. Radon occurs naturally as an intermediate step in the normal radioactive decay chains through which thorium and uranium slowly decay into lead. In nuclear industry cadmium is commonly used as a thermal neutron absorber due to very high neutron absorption cross-section of 113Cd. Titanium can be used in surface condensers. TheÂ chemical symbolÂ for Actinium isÂ Ac. MendeleviumÂ is a chemical element withÂ atomic numberÂ 101Â which means there are 101 protons and 101 electrons in the atomic structure. TitaniumÂ is a chemical element withÂ atomic numberÂ 22Â which means there are 22 protons and 22 electrons in the atomic structure.
Scandium is a silvery-white metallic d-block element, it has historically been sometimes classified as a rare-earth element, together with yttrium and the lanthanides. AluminumÂ is a chemical element withÂ atomic numberÂ 13Â which means there are 13 protons and 13 electrons in the atomic structure. ThuliumÂ is a chemical element withÂ atomic numberÂ 69Â which means there are 69 protons and 69 electrons in the atomic structure. However there are numerous exceptions; for example the lightest exception is chromium, which would be predicted to have the configuration 1s 2 2s 2 2p 6 3s 2 3p 6 3d 4 4s 2 , written as [Ar] 3d 4 4s 2 , but whose actual configuration given in the table below is [Ar] 3d 5 4s 1 .
