Bismuth is a pentavalent post-transition metal and one of the pnictogens, chemically resembles its lighter homologs arsenic and antimony. The reason behind this is lower energy orbitals are filled up first. Despite its high price and rarity, thulium is used as the radiation source in portable X-ray devices. Liquid nitrogen (made by distilling liquid air) boils at 77.4 kelvins (−195.8°C) and is used as a coolant. and Gay-Lussac, L.-J. Previously I had been asked the configuration for Fe + as an ordinary question from Periodic Table. The chemical symbol for Tungsten is W.

The chemical symbol for Erbium is Er. Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name, kohl. Sodium is an alkali metal, being in group 1 of the periodic table, because it has a single electron in its outer shell that it readily donates, creating a positively charged atom—the Na+ cation. Niobium is a soft, grey, ductile transition metal, often found in the minerals pyrochlore (the main commercial source for niobium) and columbite.

Because of its closed-shell electron configuration, its density and melting and boiling points differ significantly from those of most other lanthanides. Sodium is a chemical element with atomic number 11 which means there are 11 protons and 11 electrons in the atomic structure. 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. How do the electron configurations of transition metals differ from those of other elements? The chemical symbol for Samarium is Sm. The chemical symbol for Gold is Au. Tellurium is a brittle, mildly toxic, rare, silver-white metalloid.
