Lithium - Wikipedia

Lithium (from Greek: λίθος, romanized: lithos, lit. ''stone'') is a chemical element with the symbol Li and atomic number 3. It is a soft, silvery-white alkali metal.Under standard conditions, it is the lightest metal and the lightest solid element.Like all alkali metals, lithium is highly reactive and flammable, and must be stored in mineral oil.

Lead - Wikipedia

Lead is a chemical element with the symbol Pb (from the Latin plumbum) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point.When freshly cut, lead is silvery with a hint of blue; it tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element ...

Alkaline earth metal - Wikipedia

The alkaline earth metals are six chemical elements in group 2 of the periodic table.They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). The elements have very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure.. Structurally, they (together with helium) have in common an outer s ...

A Guide to Mercury Applications in Metalurgy

Apr 01, 2019· The primary application for mercury metal in North America and Europe is in cathode cells, which are used for the production of caustic soda. In the US, this accounts for 75% of mercury demand, although the demand for such cells has decreased 97% since 1995, as modern Chlor-alkali plants have adopted membrane cell or diaphragm cell technologies.

Lithium hydride - Wikipedia

Lithium hydride is an inorganic compound with the formula Li H.This alkali metal hydride is a colorless solid, although commercial samples are grey. Characteristic of a salt-like (ionic) hydride, it has a high melting point, and it is not soluble but reactive with all protic organic solvents. It is soluble and nonreactive with certain molten salts such as lithium fluoride, lithium borohydride ...

As with the alkali metals of Group 1 (Ia), the atoms of the alkaline-earth metals easily lose electrons to become positive ions (cations). Most of their typical compounds are therefore ionic: salts in which the metal occurs as the cation M 2+, where M represents any Group 2 atom. The salts are colourless unless they include a coloured anion ...
