Magnesium is lighter.
Magnesium is a metal. So it should be called as heavy. The correct term is more dense or denser than most other nonmetal elements. Still heavy or light is a relative term. You have to compare with other substance.
The ore rutile (impure titanium (IV) oxide) is heated with chlorine and coke at a temperature of about 900°C. Then the Titanium chloride is reduced using Magnesium and distilled to get rid of the Magnesium chloride (Magnesium atoms displaced titanium atoms). Then you get titanium.
The Kroll process is used to purify titanium metal. It involves reducing titanium tetrachloride with magnesium to produce titanium and magnesium chloride. The magnesium chloride is then removed, leaving behind purified titanium metal.
No, the Sony Vaio Titanium laptop is in fact not made from titanium, it does have a magnesium alloy casing though.

Aluminum is actually lighter than titanium
Titanium is a less reactive metal and is placed below magnesium but above iron in the reactivity series. It does not react with water or dilute acids at room temperature but can react with steam to form titanium dioxide and hydrogen gas.
i am doing homework and this is what i put: steel is extacted using a blast furnace which is quick and relatively cheap. however to extract titanium, magnesium is needed because it is more reactive. magnesium is extracted by electrolysis, which is expensive therefore it is not cheap to buy. you have to buy the magnesium to extract the titanium, which is why titanium is expensive hope this helped and you can copy it word for word i dont care :)
Magnesium burns in air and nitrogen to form magnesium oxide (MgO) and magnesium nitride (Mg3N2), respectively.
