Ever wondered which metal is the most dangerous? The most antibacterial or the rarest in the world? Austen Knapman have put together a list of the most mind-blowing facts we can think of .

#1. Iron is the most abundant metal in the universe.

#2. The most dangerous metal in the world due to its high radioactivity. It has also been linked to a number of high profile deaths and assassination due to its lethality.

#3. The Willis Tower in Chicago is the tallest steel building in the world - measuring 1,450 feet hight with 110 floors.

#4. Rhodium is probably the rarest metal in the world. There are no Rhodium mines that exist on Earth and only around 20-25 tonnes of the metal is extracted per year. It's high melting and boiling points, shiny surface and other essential properties also make it one of the most expensive metals around.

#5. Silver is the best conductor of electricity.

#6. Gold and platinum metals - amongst other elements - came from neutron stars colliding together.

#7. Silverware and brass door knobs have the ability to kill bacteria thanks to the oligodynamic effect. The process itself is not fully understood but scientists observed that metal has a toxic effect on "living cells, algae, molds, spores, fungi, viruses, prokaryotic and eukaryotic microorganisms, even in relatively low concentrations."

#8. The Eiffel Tower grows six inches taller in the summer when compared to its winter height because steel and iron expand when exposed to heat.

#9. In natural conditions, all metals are solids at room temperature apart from Mercury which exists in a liquid form.

#10. Aluminium is the most recyclable material in the world - 75% of all the aluminium produced in history is still in circulation due to recycling.
