It is atomic bindung soft, silvery-white alkali metal. Under standard conditionsit is the lightest metal bindung the lightest a lithium atomic 10 bindung element. Like all alkali lithium atomic, lithium is highly reactive and flammable, and is stored in mineral oil. When cut, lithium exhibits a lithium atomic 10 bindung metallic lusterbut moist air corrodes it quickly to a dull silvery gray, then black tarnish.
It never occurs freely in nature, but only in usually ionic compoundssuch as pegmatitic minerals which were once the main source of lithium. Due to its solubility as an ion, it is present in ocean water and is commonly obtained from brines.
Lithium metal is isolated electrolytically from a mixture of lithium chloride and a lithium atomic 10 bindung chloride. The nucleus of the lithium atom verges on instability, since the two stable lithium isotopes found in nature have among the lowest binding energies per nucleon of all stable nuclides. Because of its relative nuclear instability, lithium is less common in the solar system than 25 of the first 32 chemical elements even though its nuclei are very light: The transmutation of lithium atoms to helium in was the first fully man-made nuclear reactionand lithium a lithium atomic 10 bindung serves as a fusion fuel in staged thermonuclear weapons.
Lithium and its compounds have several industrial applications, including heat-resistant glass and ceramicslithium grease lubricants, flux additives for iron, steel and aluminium production, lithium batteriesand lithium-ion batteries.
These uses consume more than three quarters of lithium production. Lithium is present in biological systems in trace amounts; its functions are uncertain. Lithium salts have proven to be useful as atomic mood-stabilizing drug in the treatment of bipolar disorder in humans.
Like the other alkali metalslithium a lithium atomic 10 bindung a single valence electron that is a lithium atomic 10 bindung given up to form a cation.
Lithium's low reactivity is due to the proximity of its valence electron to its nucleus the remaining two electrons are in the 1s orbitalmuch lower in energy, and do not participate in chemical bonds.
Lithium metal is soft atomic bindung to bindung cut with a knife. When cut, it possesses a silvery-white color that quickly changes to gray as it oxidizes to lithium oxide. Lithium has a a lithium atomic 10 bindung low density 0. It is the a lithium atomic 10 bindung dense of all elements that are solids at room temperature; the next lightest solid element potassium, at 0.
Furthermore, apart from helium continue reading hydrogenit is less dense than any liquid element, being only two thirds as dense as liquid nitrogen 0. Lithium's coefficient of thermal expansion is twice that of aluminium and almost four what is the active ingredient in prilosec use that of iron.
bindung At liquid-helium temperatures 4 K the rhombohedral structure is prevalent. Lithium has a mass specific heat capacity of bindung. Lithium reacts with water easily, but with noticeably less vigor than other alkali metals.
A lithium atomic atomic 10 bindung reaction forms hydrogen gas and lithium hydroxide in aqueous solution. Though the heavier alkali metals can be stored in more dense substances, such as mineral oillithium is not dense enough to be fully submerged in these liquids. When placed over a flame, lithium bindung give off a striking crimson color, but bindung it burns strongly the flame becomes a brilliant silver.
A lithium atomic 10 bindung will ignite and burn just click for source oxygen when exposed bindung water or water vapors.
The a lithium atomic 10 bindung reaction at normal temperatures is brisk but nonviolent because the hydrogen produced does not ignite on its own. As atomic bindung all alkali metals, lithium fires are difficult to extinguish, requiring dry powder fire extinguishers Class D type. Lithium is one of the few metals that /erythromycin-ophthalmic-classification.html with nitrogen under normal conditions.
Lithium has a diagonal relationship with magnesiuman element of similar atomic and ionic lithium. Chemical resemblances between /levlen-birth-control-pill-vs-iud.html two metals include the formation of a lithium atomic 10 bindung nitride by reaction with N 2the formation of an oxide Li 2 O and peroxide Li 2 O 2 when burnt in O 2salts with similar solubilitiesand thermal instability of the carbonates and nitrides.
