About Sodium Cyclopentadienylide

Sodium Cyclopentadienylide is one of numerous organometallic compounds manufactured by American Elements under the trade name AE Organometallics™. Sodium cyclopentadienylide (NaCp) can be used as a precursor in the synthesis of various metallocene and cyclopentadienyl metal complexes. Organometallics are useful reagents, catalysts, and precursor materials with applications in thin film deposition, industrial chemistry, pharmaceuticals, LED manufacturing, and others. American Elements supplies organometallic compounds in most volumes including bulk quantities and also can produce materials to customer specifications. Most materials can be produced in high and ultra high purity forms (99%, 99.9%, 99.99%, 99.999%, and higher) and to many standard grades when applicable including Mil Spec (military grade), ACS, Reagent and Technical Grades, Pharmaceutical Grades, Optical, Semiconductor, and Electronics Grades.

Sodium Bohr ModelSee more Sodium products. Sodium (atomic symbol: Na, atomic number: 11) is a Block D, Group 5, Period 4 element with an atomic weight of 22.989769. The number of electrons in each of Sodium's shells is [2, 8, 1] and its electron configuration is [Ne] 3s1.The sodium atom has a radius of 185.8 pm and a Van der Waals radius of 227 pm. Sodium was discovered and first isolated by Sir Humphrey Davy in 1807. In its elemental form, sodium has a silvery-white metallic appearance. It is the sixth most abundant element, making up 2.6 % of the earth's crust. Sodium does not occur in nature as a free element and must be extracted from its compounds (e.g., feldspars, sodalite, and rock salt). The name Sodium is thought to come from the Arabic word suda, meaning "headache" (due to sodium carbonate's headache-alleviating properties), and its elemental symbol Na comes from natrium, its Latin name.
