One meter is a length measurement, equal to 3.28 feet. You can test this using a meter stick and 1 foot (12 inch) rulers. Lay the meter stick on the ground, and place the rulers end-to-end next to it. Three rulers (3 feet) will almost be as long as the meter stick.
Characteristics: Uses: Magnesium is a silvery-white, low density, reasonably strong metal that tarnishes in air to form a thin oxide coating. Magnesium and its alloys have very good corrosion resistance and good high temperature mechanical properties.The metal reacts with water to produce hydrogen gas.When it burns in air, magnesium produces a brilliant white light. The brilliant light it produces when ignited is made use of in photography, flares, pyrotechnics and incendiary bombs.agnesium and its alloys have very good corrosion resistance and good high temperature mechanical properties.

Magnesium is more reactive than iron. So Magnesium loses electrons in preference to iron. Magnesium reacts with the oxygen in the air to form Magnesium Oxide, and the iron remains protected, because it has magnesium attached to it. Magnesium is oxidised as it dissolves. Iron ions are reduced to iron atoms. The iron ions take the electrons given out by magnesium, and form iron metal.
