Are there any similarities between Magnesium and Tin?
Well, they are both metals and elements of main groups. Magnesium oxydation number is II and Tin oxydation numbers are II and IV.
They are both shinny. :lol:
Both elements are metals and therefore reasonably good conductors of heat and electricity. Both have fairly low melting points (you can melt them on the kitchen stove) and are fairly reactive in common inorganic acids such as HNO3 or HCl. The resulting compounds have a fairly wide range of applications in everyday life. Magnesium sulfate (MgSO4) is epsom salts used as a bath soak and laxative; stannous fluoride (SnF) is a decay-preventative in some toothpastes; magnesium carbonate is gymnasts' chalk, used to improve the grip when vaulting on the horse or parallel bars. Tin oxide is used as a polishing compound. Both metals have wide application in alloying. Magnesium is alloyed with aluminum to produce a lighhter and tougher metal used in mag wheels on performance cars; tin is essential in type metal, white metal, pewter and many other alloys. Both metals are bivalent (thus forming compounds like MgCl2/SnCl2 or MgO or SnO) though Sn is also tetravalent (forming compounds like SnCl4 and SnO2) This is what your previous correspondents are correct in observing that both having an oxidation number of II (and tin also one of IV) and that, when freshly cut, both are shiny, though neither wins any prizes for spelling.
I would be cautious about trying to melt Mg though; at red heat it combines with O2 in a vigorous exothermic reaction to produce a spectacular white light light (used in flares and fireworks) which is incredibly rich in UV radiation. Eye damage may result. They never told me these things when I was a child with my very own chemistry set, ingots of Mg and flasks of Hg many years ago.
