What is the most common metal found on earth?
Correct answer: Aluminium
YMCA79
Pretty disgusting we only manage to recycle half! Must do better!
Syr Hal
In Paragraph 2 you say it is “so chemically reactive,” then in para 5 you talk about its “low reactivity.” Which is it to be?
ThandQ
While safe for covering food, be sure it's not acidic. Like spaghetti sauce, tomato sauce. The aluminium foil will develop holes and contaminate the food it is covering.

amazing earth

Syr Hal, that's a very good question ,the answer is that it's very reactive. Metallic aluminium exposed to air is that it rapidly forms an oxide layer , that is generally foodsafe .. only strong acids and alkali would attack it. But soft drink cans are lined with plastic,because soft drinks are very acid. aluminium pots ,pans,cups have a limited life due to chemical attack and mechanical erosion ( scratches,dents,cracking)

Did you know planes are made from aluminium because it is the lightest metal and it is strong enough to hold whilst being lifted off the earth at amazing speeds :)

glad to see aluminium spelled correctly
Birdiemom
[bobbo16], was it the spelling that threw you off? That's how the British spell it. It is a metallic element.
Which Tyler
Syr Hal, Aluminium is very reactive, Aluminium Oxide is very unreactive. Aluminium Oxide is what you get when Aluminium is exposed to air, which forms a layer protecting the metal underneath.

Olly, the yanks spell and pronouce a lot of words incorrectly
Player #125843019
palitja, me too
PerkyLin
Player #66817220, It specified metal.

Guillermo Jr. - Well, you know, we mostly are a very posh race! In fact, you could say that that is why we tend to look down on Yankees calling it "al-oom-inum"! (Hmm - I should also add, as you would say - "lol"!)
Ken
one of the easiest metals to recycle, so why are 50 billion not being recycled?
Peter
Aluminium is the most abundant metal in the earth's crust. If you count the whole earth it is iron, as the earth's core is an iron ball.
Player #66817220
I was looking for hydrogen, which is the most abundant element in the universe and is mostly what comprises water.

Syr Hal, many elements have different reactivity depending on what state they are in. Metals can be in a metalic state or an ionic state. As a metal they have all their electrons and share the outermost ones back and fourth between each other making a strong but relatively flexible bonds. Aluminum makes a fairly strong and flexible bound that allows it to bend but not break and as a metal those metallic bonds are not easily broken. However, as an ion, aluminum loses its outermost electrons and doesn't make metallic bounds anymore.

Vladan, pretty sure it's the 3rd most on earth that is according to Neil degasse Tyson and he's a pretty smart dude
Vladan
most abundant in Earth's crust isnt the same as most common on Earth.
Qatwalk
Little Saint, It is aluminum in US and Canada, and aluminium in the rest of the anglophone world. Do you Brits pronounce it "nyum" at the end?
I like the differences between the different dialects. They are interesting.
Player #46304857
Syr Hal, I picked up on that too.
wileycoyote
How come there's an extra "i" on the last syllable? I'm sure it's spelled "aluminum" on the packaging of most aluminum foils.
Tom
Syr Hal, Aluminium metal is very reactive and the dull grey surface is due to Aluminium Oxide layer.
Later Aluminium foil is being discussed, which is said to 'low reactivity'. But this is due to a surface layer added during manufacture.
Player #34952961
I would say that the
answer should be Iron.
Sully Girl
Syr Hal, yeah I wondered that, seems to be conflicting information
Guillermo Jr.
I dig how the Brits call it
"Al-you-min-ee-um"
makes it sound more posh..
Mari
I am surprised. I thought it was the most common element
Player #25874027
EcLyPzEGsX99, it doesn’t but Aluminium mighty
Player #23307308
YMCA79, it is not as bad as plastic. atleast it comes from earth and goes back in.
Player #5100533
YMCA79, The next Highest answer was GOLD. Who thinks Gold is one of the most abundant metals on earth??? JEEESH !!
Player #10856472
This is wrong. The most common metal on earth is iron, by a long way.
Ironstine
Player #2867640, it's not the lightest metal (when considering a pour of the pure element .) . it's strong , it's tough ( elastic,up to a point ,and tough means that point takes more energy to get to than most other) and then you can do strength for weight ...and find it's better than steel

YMCA79, Laziness.
McShaneGun
Syr Hal, I thought the same lol I came here to learn not to be confused
SQinfoNUTS
Syr Hal, I also found this confusing. I read it twice and it does seem to contradict itself.
