∙ 13y agoThe three hardest substances on Earth are in order:
1. Lonsdaleite**
2. Aggregated Diamond NanoRods ~ ADNR ---Diamond structured, man- made nano rods.
3.Synthesized Fullerines ~ Fullerine family made Ultra- hard with modern science.
Number 2 and 3 are allotropes of Carbon because Carbon is the ideal element because of its atomic number (4 electrons in outer shell = 4 single convalent bonds to make 8) and because of its compact structure. It's outer shell is closest to its nucleus in it's group and period in the Periodic Table.
**Lonsdaleite can only be found when certain meteorites crash into the Earth. Scientists have discovered that this substance is about %58 harder than diamond.
