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
Extraordinary assumptions and hypothetical conditions an appraiser identify specific assignment elements in the planning of an appraisal assignment and gather and analyze information about those elements, including assignment conditions, which include assumptions, extraordinary assumptions, hypothetical conditions, and hypothetical conditions. Additionally, all USPAP standards dealing with the development of appraisals, consulting, or mass appraisal specifically require that any extraordinary assumptions and any hypothetical conditions necessary in the assignment be identified in the course of formulating the appraisal problem and planning the scope of work. Under USPAP, an appraisal may be predicated on extraordinary assumptions only under certain conditions, specifically Similarly, an appraisal may also be predicated
