Period 2 element two make up all natural occurrence of lithium on Earth, although further isotopes have been synthesized. In ionic compounds, lithium loses an electron to become positively charged, forming the cation Li. Lithium is the first alkali metal in the periodic table, and the first metal of any kind in the periodic table. At standard temperature and pressure, lithium is a soft, silver-white, highly reactive metal. With a density of 0.564 g·cm, lithium is the lightest metal and the least dense solid element. Lithium is one of the few elements synthesized in the Big Bang, making it a primordial element. Lithium
Data element data representation, a collection of data elements forms a data structure. In practice, data elements (fields, columns, attributes, etc.) are sometimes "over loaded", meaning a given data element will have multiple potential meanings. While a known bad practice, overloading is nevertheless a very real factor or barrier to understanding what a system is doing. Data element In metadata, the term data element is an atomic unit of data that has precise meaning or precise semantics. A data element has: Data elements usage can be discovered by inspection of software applications or application data files through a process of manual or
