As the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine. Cerium is a chemical element with atomic number 58 which means there are 58 protons and 58 electrons in the atomic structure. A percentile rank for the political stability of the top producing country, derived from World Bank governance indicators.

Oxidation state 0 occurs for all elements – it is simply the element in its elemental form. Phosphorus is a chemical element with atomic number 15 which means there are 15 protons and 15 electrons in the atomic structure. The number of electrons in each element’s electron shells, particularly the outermost valence shell, is the primary factor in determining its chemical bonding behavior.

This list of electron configurations of elements contains all the elements in increasing order of atomic number.. To save room, the configurations are in noble gas shorthand. Titanium is resistant to corrosion in sea water, aqua regia, and chlorine.

Equally important is their low toxicity. A list of reference sources used to compile the data provided on our periodic table of elements can be found on the main periodic table page. 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”.

1) You may use almost everything for non-commercial and educational use. [49] Further, zirconium is commonly used in commercial products (e.g. Density (g cm−3)


Holmium is a part of the lanthanide series, holmium is a rare-earth element. Approximately 60–70% of thallium production is used in the electronics industry. Zirconium metal is protected by a thin oxide layer making it exceptionally resistant to corrosion by acids, alkalis and seawater. This fact has key implications for the building up of the periodic table of elements. This is approximately the sum of the number of protons and neutrons in the nucleus. The ordering of the electrons in the ground state of multielectron atoms, starts with the lowest energy state (ground state) and moves progressively from there up the energy scale until each of the atom’s electrons has been assigned a unique set of quantum numbers. Uncombined elements have an oxidation state of 0.

Prairie Dog Control: Non-Lethal Techniques. 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.

It is occasionally found in native form as elemental crystals. Sodium is a soft, silvery-white, highly reactive metal. Major advantage of lead shield is in its compactness due to its higher density. Because of its closed-shell electron configuration, its density and melting and boiling points differ significantly from those of most other lanthanides. The transition of a substance directly from the solid to the gas phase without passing through a liquid phase.
