Lithium and magnesium have a diagonal relationship due to their similar atomic radii, [5] so that they show some similarities. For example, lithium forms a stable nitride , a property common among all the alkaline earth metals (magnesium's group) but unique among the alkali metals. [ 84 ]
These pairs (lithium (Li) and magnesium (Mg), beryllium (Be) and aluminium (Al), boron (B) and silicon (Si), etc.) exhibit similar properties; for example, boron and silicon are both semiconductors, forming halides that are hydrolysed in water and have acidic oxides.
Magnesium and calcium are ubiquitous and essential to all known living organisms. They are involved in more than one role, with, for example, magnesium or calcium ion pumps playing a role in some cellular processes, magnesium functioning as the active center in some enzymes, and calcium salts taking a structural role, most notably in bones.
However, a team of scientists at the Joint Center for Energy Storage Research have just discovered a fast magnesium-ion solid-state conductor that will go a long way towards making non-flammable ...
Lithium Li Li + Barium Ba Ba 2+ Strontium Sr Sr 2+ Calcium Ca Ca 2+ Magnesium Mg Mg 2+ reacts very slowly with cold water, but rapidly in boiling water, and very vigorously with acids: Beryllium Be Be 2+ reacts with acids and steam Aluminium Al Al 3+ Titanium Ti Ti 4+ reacts with concentrated mineral acids: pyrometallurgical extraction using ...
Notable examples include alkali metals, lithium through caesium, and alkaline earth metals, magnesium through barium. Some water-reactive substances are also pyrophoric, like organometallics and sulfuric acid. The use of acid-resistant gloves and face shield is recommended for safe handling; fume hoods are another effective control of such ...
Lithium and then potassium are the two lightest metallic elements. Magnesium , aluminium and titanium alloys are light metals of significant commercial importance. [ 2 ] Their densities of 1.7, 2.7 and 4.5 g/cm 3 range from 19 to 56% of the densities of other structural metals, [ 3 ] such as iron (7.9) and copper (8.9).
Lithium-6 is valued as a source material for tritium production and as a neutron absorber in nuclear fusion. Natural lithium contains about 7.5% lithium-6 from which large amounts of lithium-6 have been produced by isotope separation for use in nuclear weapons. [189] Lithium-7 gained interest for use in nuclear reactor coolants. [190]
