My favourite is Carbon! It’s so versatile! In various different forms (allotropes) it is:
-Diamond (the hardest known material)
-Graphene (the thinnest material at one atom thick!)
-Carbon nanotubes (strongest and stiffest material discovered)
And of course, adding it to iron gives you steel – which is used extensively in engineering! It’s so great in so many different ways 😀
