Non-Metals in Nature: Diamond and Coal Examples #3695641 (License: Personal Use)

The image contrasts two naturally occurring non-metals: a faceted, transparent diamond showcasing its crystalline lattice and optical brilliance, and a rough pile of black coal representing amorphous carbon with high carbon content. Though both consist primarily of carbon, their atomic arrangements lead to dramatically different physical properties-diamond is the hardest natural substance, while coal is soft and combustible.

This image is typically used in educational science content-especially middle or high school chemistry or geology-to illustrate allotropes of carbon and the diversity within non-metal elements. It supports user intent to understand classification, physical properties, and real-world examples of non-metals.
