Magnesium....hmmm?
what are some more physical properites of magnesium? and where does its symbol come from?and what are some chemical properties?
i'm a little confused
Answer:
Elemental magnesium is a fairly strong, silvery-white, light-weight metal (two thirds the density of aluminium). It tarnishes slightly when exposed to air, although unlike the alkaline metals, storage in an oxygen free environment is unnecessary because magnesium is protected by a thin layer of oxide which is fairly impermeable and hard to remove.Like its lower periodic table group neighbor calcium, magnesium reacts with water at room temperature, though it reacts much more slowly than calcium. When it is submerged in water hydrogen bubbles will almost unnoticably begin to form on the surface of the metal, though if powdered it will react much more rapidly. Magnesium also reacts with hydrochloric acid and produces heat and hydrogen when added to it. The magnesium will begin to bubble and become hot, too hot to touch comfortably. The reaction will occur faster with higher temperatures (see precautions). Magnesium is a highly flammable metal, but while it is easy to ignite when powdered or shaved into thin strips, it is difficult to ignite in mass or bulk. Once ignited it is difficult to extinguish, being able to burn in both nitrogen (forming magnesium nitride), and carbon dioxide (forming magnesium oxide and carbon).
Magnesium, when it burns in air, produces a brilliant white light. This was used in the early days of photography when magnesium powder was used as a source of illumination (flash powder). Later, magnesium ribbon was used in electrically ignited flash bulbs. Magnesium powder is still used in the manufacture of fireworks and marine flares where a brilliant white light is required.
Magnesium, when glowing white, has many chemical properties that it does not possess at lower temperatures. It also becomes more toxic, although this is of little practical importance, because the high temperature alone generally prevents human contact.
magnesium is good conductor of electricity, it is ductile(can be strectchedout into thin wires) and it has lustre. some of the chemical properties of Mg are ; when burnt in the presence of air it produces an oxide of the metal. magnesium react with acids to produce a Mg salt and hydrogen gas and reacts with water to produce an hydroxide of Mg and hydrogen gas
