These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f). The origin of the name comes from the Greek word lithos meaning stone, apparently because it was discovered from a mineral source whereas the other two elements, sodium and potassium, were discovered from plant sources.It is a soft silvery-white metal and it's the lightest of metals. Atomic number
Lithium oxide goes into glass and glass ceramics. 2. Making Pu. The periodic table, also known as the periodic table of elements, arranges the chemical elements such as hydrogen, silicon, iron, and uranium according to their recurring properties.

Lithium is used as lubricant greases worldwide. In the periodic table, it is located in group 1, among the alkali metals. Once lithium's discovery had been announced others soon found it to be present in all kinds of things such as grapes, seaweed, tobacco, vegetables, milk and blood. The ground state electronic configuration of neutral lithium is [ He ]. It cannot be kept under oil, as sodium can, because it is less dense and floats.
Lithium in its pure form is a soft, silver white metal, that tarnishes and oxidizes very rapidly in air and water. It is the lightest of the metals, with a density approximately half that of water. Period 1, which only contains two elements (hydrogen and helium), is too small to draw any conclusive trends from it, especially because the two elements behave nothing like other s-block elements.

This is calculated by combining the scores for crustal abundance, reserve distribution, production concentration, substitutability, recycling rate and political stability scores. It is a member of the chalcogen group on the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds. For all elements in period 2, as the atomic number increases, the atomic radius of the elements decreases, the electronegativity increases, and the ionization energy increases. The subshells are labeled with letters (s, p, d, and f) and the shells are labeled with numbers. High = substitution not possible or very difficult. The role of the element in humans, animals and plants. He had injected guinea pigs with a 0.5% solution of lithium carbonate, and to his surprise these normally highly-strung animals became docile, and indeed were so calm that they would sit in the same position for several hours. Storing it is a problem. It is toxic, except in very small doses. Lithium on the periodic table is a chemical element among the alkali metals, and is the least dense solid element. Lithium was discovered in the mineral petalite (LiAl(Si 2 O 5) 2) by Johann August Arfvedson in 1817.It was first isolated by William Thomas Brande and Sir Humphrey Davy through the electrolysis of lithium oxide (Li 2 O). Lithium on the Periodic Table. Lithium chloride is highly hygroscopic (ability to absorb moisture from air) and are used as desiccants for gas streams. However, in small doses it is prescribed as a treatment for manic depression (now called bipolar disorder). This longevity has been extended to lithium batteries of the more common 1.5-volts variety (in which the cathode is iron disulfide) that are in everyday gadgets such as clocks, and lithium is now beginning to be used for rechargeable batteries, Lithium is a soft, silvery-white, metal that heads group 1, the alkali metals group, of the periodic table of the elements.
