is magnesium or aluminum more active?

Mg more reactive than Al cuz it has lesser valence electrons to release,making it easier to achieve stable noble gas configuration

Copper has a higher melting and boiling point and better electrical conductivity.\n\nIf you are a die caster, Zinc would be better because it can be easily pressure die-cast and hence better accuracy in the cast component with minimal metal removal for finishing.

Aluminum is more reactive.\nSome times you are suposed to look up some of the homework to learn how to solve problems\n. There is a chart of activities of elements, also knowledge of the periodic table shows whi are more reactive

manesiun and fluorine....magnesium forms a positively charged ion, while fluorine forms a negatively charged ion, different charges attract, so they form ionic bond to each other forming a ionic compound.\n\nnitrogen and sulphur both form negative charged ions, so there is noway to make them react unless in a prescence of a catalyst.\n\nionic compounds generally fom using, metals and nonmetals. magnesium is a metal, and fluorine nitrogen and sulphur are all non metals

In Be and Mg only the s subshell is full while the p is completely vacant. Moreover for every element the most stable state is tht of the nearest noble gas configuration. So for Be and Mg it will be quite easy to give to 2 electrons to get the nearest noble gas configuration to make stable cations. Hence they are not inactive/inert. Also they can gain electron pairs in the p-subshell (although it is energetically not favourable) so they can not be inert.

Magnesium. Very dangerous around extreme heat as once it is ignited you can not put it out. The military use to cast it for their brakes for their fighter jets because magnesium is so light. However, high speed landings and hot brakes could cause ignition.

Mg, magnesium, which will act as a sacrificial anode and corrode in preference to the iron, which becomes the cathode in the cell formed by the two metals and the conducting earth. The piece of Mg must also be underground and nearby. See the ref.

Zinc is by far the best element. I also like plutonium.  It's just fun to say. "Plutonium."

Of the ones you listed Aluminum would be the best mostly because it is a metal.

magnesium is used to make glass for high rise buildings.  It makes the glass strong, it is harder to break magnesium enhanced glass.

The first answer is, like, SO wrong. Gold is one of the least active metals. Check out the Activity Series of metals (you can Google it). The ones at the top of the list (lithium, calcuim, and barium, I think) are the most reactive. They'd react readily with air (they oxidize, releasing hydrogen gas from the water vapor in the atmosphere, forming an oxide or hydroxide). They'd definitely cause an explosion when reacted with acids. Even sodium metal (not salt, I'm talking pure sodium) will react with acids violently.\n\nAll metals react with acids to some degree. Even gold, the most unreactive metal, dissolves in selenic acid. Silver reacts best with nitric acid to form silver nitrate. The coinage metals (Au, Ag, Cu) are the most unreactive.

I would say Aluminum Chloride. (AlCl3)

All active metals whose activity is more than H react with water under some or the other condition. For eg. Na metal reacts violently with cold water(the colder the better) liberating hydrogen gas which ignites due to the heat produced in the reaction whereas Mg shows a similar reaction with hot water. The energy liberated is due to the Hydration enrgy which gives the respective metal hydroxides. Even dissolution is a slightly exothermic.

It is not a combination of iron and tin, or anything else besides protons, electrons, and neutrons.\n\nThere's a naturally occurring ore called bauxite, which was discovered near Les Baux in the south of France, which is refined to produce aluminum.\n\nAt this link   \n\nhttp://volcano.und.edu/vwdocs/minerals/bauxite.html\n\nthere's a pie chart showing where it is mined today.  A lot of it comes from Australia, but that's not the only source.

Sodium, Potassium, Barium\n\n As long as the metal is more reactive than magnesium, it will be able to displace magnesium ion.
