Diamond and graphite are both made entirely of which single element?

Explanation

Diamond and graphite are both allotropes of carbon, meaning they are made of the same element but with atoms arranged in different structures. In diamond, carbon atoms form a rigid three-dimensional lattice, making it extremely hard, while in graphite atoms form layered sheets that slide easily past each other, making it soft and useful as a lubricant or pencil lead. This shows how the arrangement of atoms, not just the element itself, determines a material’s physical properties. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
