As the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.Neon is a colorless, odorless, inert monatomic gas under standard conditions, with about two-thirds the density of air.Sodium is a soft, silvery-white, highly reactive metal. In writing the electron configuration for Potassium the first two electrons will go in the 1s orbital.

Each element has a unique atomic structure that is influenced by its electronic configuration, which is the distribution of electrons across different orbitals of an atom.

Its abundance in rocky planets like Earth is due to its abundant production by fusion in high-mass stars.Cobalt is found in the Earth’s crust only in chemically combined form, save for small deposits found in alloys of natural meteoric iron. Gallium does not occur as a free element in nature, but as gallium(III) compounds in trace amounts in zinc ores and in bauxite.Germanium is a lustrous, hard, grayish-white metalloid in the carbon group, chemically similar to its group neighbors tin and silicon. Francium is the second-least electronegative element, behind only caesium, and is the second rarest naturally occurring element (after astatine).

This article provides you with an electronic configuration chart for all these elements.There are 118 elements in the periodic table. Two representations of the distribution of electrons in the potassium atom are shown.
Arsenic is a metalloid.Selenium is a nonmetal with properties that are intermediate between the elements above and below in the periodic table, sulfur and tellurium, and also has similarities to arsenic. In fact their absorption cross-sections are the highest among all stable isotopes.Terbium is a silvery-white, rare earth metal that is malleable, ductile, and soft enough to be cut with a knife. The N shell containing 4s, 4d, 4p and 4f, can carry 32 electrons. It is even less abundant than the so-called rare earths. Although neodymium is classed as a rare earth, it is a fairly common element.Promethium is one of only two such elements that are followed in the periodic table by elements with stable forms. Possible oxidation states are +1. The p orbital can hold up to six electrons. It is a noble metal and a member of the platinum group.Palladium, platinum, rhodium, ruthenium, iridium and osmium form a group of elements referred to as the platinum group metals (PGMs). Model 1 because it shows an electron … If you continue to use this site we will assume that you are happy with it. Iodine is the least abundant of the stable halogens, being the sixty-first most abundant element.
The chemical properties of this silvery gray, crystalline transition metal are intermediate between rhenium and manganese.Ruthenium is a rare transition metal belonging to the platinum group of the periodic table. and Gay-Lussac, L.-J.Discoverer: Priestley, Joseph and Scheele, Carl WilhelmDiscoverer: Ramsay, Sir William and Strutt, John (Lord Rayleigh)Discoverer: Del Rio, Andrés Manuel (1801) and Sefström, Nils Gabriel (1830)Discoverer: Ramsay, Sir William and Travers, MorrisDiscoverer: Bunsen, Robert Wilhelm and Kirchhoff, Gustav RobertDiscoverer: Reich, Ferdinand and Richter, HieronymusDiscoverer: Ramsay, William and Travers, Morris WilliamLanthanoids comprise the 15 metallic chemical elements with atomic numbers 57 through 71, from lanthanum through lutetium. In this list the orbitals in parentheses are not occupied in the ground state of the heaviest atom now known (The aufbau principle can be applied, in a modified form, to the The outermost electron shell is often referred to as the "valence shell" and (to a first approximation) determines the chemical properties.
They stand for sharp (S), principal (P), diffuse (D), and fundamental (F).
Such an arrangement helps explain the periodicity and periodic trends observed across the elements of the periodic table. Neptunium is the first transuranic element.Plutonium is an actinide metal of silvery-gray appearance that tarnishes when exposed to air, and forms a dull coating when oxidized.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.Curium is a hard, dense, silvery metal with a relatively high melting point and boiling point for an actinide.Berkelium is a member of the actinide and transuranium element series.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). Therefore the Potassium electron configuration will be 1s The configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom. The periodic table is a tabular display of the chemical elements organized on the basis of their atomic numbers, electron configurations, and chemical properties. In nuclear industry cadmium is commonly used as a thermal neutron absorber due to very high neutron absorption cross-section of 113Cd. Electronic configurations describe each electron as moving independently in an orbital, in an average field created by all other orbitals. Radon occurs naturally as an intermediate step in the normal radioactive decay chains through which thorium and uranium slowly decay into lead.Francium is an alkali metal, that has one valence electron. For example, silicon has nine possible integer oxidation states from −4 to +4, but only -4, 0 and +4 are common oxidation states.With a standard atomic weight of circa 1.008, hydrogen is the lightest element on the periodic table.
