One non-metal that is very hard is diamond. Diamond is made of carbon atoms arranged in a crystal structure, making it the hardest known natural material.
Francium is considered the hardest metal in Group 1 (alkali metals). It is the most reactive alkali metal and is very rare in nature. Due to its high reactivity and radioactive nature, it is challenging to study and handle francium.
Diamond is the hardest of the metals listed, as it ranks the highest on the Mohs scale with a rating of 10. Aluminium, silver, and platinum are not classified as metals on the Mohs scale, and they are not as hard as diamond.
Tungsten is the hardest naturally occurring metal on Earth, while copper is one of the cheapest metals that can conduct electricity efficiently. Tungsten is often used in applications requiring high hardness and resistance to heat, whereas copper is widely used in electrical wiring and electronics due to its excellent conductivity.
this Submarine can not break of water pressure because it is made of the hardest metal in the world!
Lutemium
There is no metal by the name 'thompson'.
Caesium (or cesium) is the softest metal.
yes it is
titanium
tungsten
Chromium is the hardest metal; the Mohs hardness of osmium is 7 and the Mohs hardness of chromium is 8,5.
diamond
smash one into the other, the hardest will damage or break the soffest
If you mean literally hard, then metal coins (found in many countries) would be the hardest.
