And so we follow the usual "Aufbau scheme"... underbrace(1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)4s^(2)3d^1)_"electronic configuration of scandium metal" underbrace(1s^(2)2s^(2)2p^(6)3s^(2)3p^(6))_"electronic configuration of scandium trication" The chemical symbol for Selenium is Se. The chemical symbol for Scandium is Sc. The maximum electrons that can be carried by the sub-shell S is 2, by P is 6, by D is 10, and the F sub-shell can carry 14. Manganese is a metal with important industrial metal alloy uses, particularly in stainless steels. The chemical symbol for Manganese is Mn. Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant. Indium is a post-transition metal that makes up 0.21 parts per million of the Earth’s crust. Electron Configuration Chart for All Elements in the Periodic Table. The chemical symbol for Terbium is Tb. Electron Configuration and Oxidation States of Scandium. Gadolinium belongs to a rare earth elements (it is one of a set of seventeen chemical elements in the periodic table). This means part of the electron configuration has been replaced with the element symbol of the noble gas symbol. Osmium is a hard, brittle, bluish-white transition metal in the platinum group that is found as a trace element in alloys, mostly in platinum ores. Like the other metals of the platinum group, ruthenium is inert to most other chemicals. Although classified as a rare earth element, samarium is the 40th most abundant element in the Earth’s crust and is more common than such metals as tin. Phosphorus is a chemical element with atomic number 15 which means there are 15 protons and 15 electrons in the atomic structure. The chemical symbol for Krypton is Kr. These condensers use tubes that are usually made of stainless steel, copper alloys, or titanium depending on several selection criteria (such as thermal conductivity or corrosion resistance). Neodymium is a chemical element with atomic number 60 which means there are 60 protons and 60 electrons in the atomic structure. Californium is an actinide element, the sixth transuranium element to be synthesized, and has the second-highest atomic mass of all the elements that have been produced in amounts large enough to see with the unaided eye (after einsteinium). In some respects zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size. A major development was the discovery that steel could be made highly resistant to corrosion and discoloration by adding metallic chromium to form stainless steel. Bismuth is a brittle metal with a silvery white color when freshly produced, but surface oxidation can give it a pink tinge. Even though its electron configuration is a bit different, scandium still wants to bond with those three extra electrons, no matter what shell they are in. It has remarkable resistance to corrosion, even at high temperatures, and is therefore considered a noble metal. Rubidium is a chemical element with atomic number 37 which means there are 37 protons and 37 electrons in the atomic structure. The chemical symbol for Neodymium is Nd. Oxidation states are typically represented by integers which may be positive, zero, or negative. Discoverer: Davy, Sir H. and Thénard, L.-J. Platinum is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal. The chemical symbol for Mendelevium is Md. It is an extremely reactive element and a strong oxidising agent: among the elements, it has the highest electron affinity and the third-highest electronegativity, behind only oxygen and fluorine. Caesium is a soft, silvery-gold alkali metal with a melting point of 28.5 °C, which makes it one of only five elemental metals that are liquid at or near room temperature. Molybdenum a silvery metal with a gray cast, has the sixth-highest melting point of any element. Scandium (Sc), chemical element, a rare-earth metal of Group 3 of the periodic table. It could be part of the main body, but then the periodic table would be rather long and cumbersome. It is by mass the most common element on Earth, forming much of Earth’s outer and inner core. 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. Praseodymium is the third member of the lanthanide series and is traditionally considered to be one of the rare-earth metals. Its boiling point is the lowest among all the elements. Chlorine is a yellow-green gas at room temperature. Because of its closed-shell electron configuration, its density and melting and boiling points differ significantly from those of most other lanthanides. The chemical symbol for Titanium is Ti. Tellurium is a brittle, mildly toxic, rare, silver-white metalloid. The chemical symbol for Iodine is I. Iodine is the heaviest of the stable halogens, it exists as a lustrous, purple-black metallic solid at standard conditions that sublimes readily to form a violet gas. Holmium is a relatively soft and malleable silvery-white metal. Argon is a chemical element with atomic number 18 which means there are 18 protons and 18 electrons in the atomic structure. 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. Each shell and subshell have a limitation on the amount of electrons that it can carry. Tungsten is an intrinsically brittle and hard material, making it difficult to work. Also in some tin and tungsten ores. The first alloy used on a large scale was bronze, made of tin and copper, from as early as 3000 BC. Rhenium is a silvery-white, heavy, third-row transition metal in group 7 of the periodic table. The chemical symbol for Lutetium is Lu. Only about 5×10−8% of all matter in the universe is europium. The chemical symbol for Tin is Sn. Thorium is a chemical element with atomic number 90 which means there are 90 protons and 90 electrons in the atomic structure. In nuclear industry gadolinium is commonly used as a neutron absorber due to very high neutron absorbtion cross-section of two isotopes 155Gd and 157Gd. All of the alkali metals have a single valence electron in the outer electron shell, which is easily removed to create an ion with a positive charge – a cation, which combines with anions to form salts. Similarly, the p block are the right-most six columns of the periodic table, the d block is the middle 10 columns of the periodic table, while the f block is the 14-column section that is normally depicted as detached from the main body of the periodic table. It is the Pauli exclusion principle that requires the electrons in an atom to occupy different energy levels instead of them all condensing in the ground state.
