Nonmetals generally have low melting points compared to metals. This characteristic is due to the nature of the bonding and atomic structure found in nonmetals. Nonmetals typically form covalent bonds, which are weaker than the metallic bonds found in metals. Consequently, less energy is required to break these bonds, resulting in lower melting points.
For example, elements like sulfur and phosphorus are nonmetals that melt at relatively low temperatures. In contrast, some nonmetals, like diamond (a form of carbon), can have high melting points, but this is largely due to its unique structure rather than common characteristics of nonmetals as a whole.
In summary, while there are exceptions, most nonmetals tend to have lower melting points compared to metals, making them easier to melt under standard conditions.
