WebMar 31, 2024 · Toughness measure's a metal's ability to maintain its integrity while being pressed, pulled, or deformed. A metal that can be bent without breaking is tougher than a metal that will break rather than bend. Hardness is a measure of a metal's ability to withstand friction and thus avoid abrasion. A diamond, for example, is very hard. WebAug 22, 2024 · Brittleness A much clearer distinction between nonmetals and metals is shown when the brittleness of the elements is considered. Carbon in its diamond allotrope is very hard, reflecting the strength of the covalent bonds. However, if a diamond is hit with a hammer, it shatters.
