What is one characteristic that distinguishes metals from non-metals?

One characteristic that clearly distinguishes metals from non-metals is that metals typically have high melting points. This property is primarily due to the strong metallic bonds formed between metal atoms. In metals, atoms are arranged in a lattice structure, where each atom shares its outermost electrons with many others, creating a strong bond that requires significant energy to break. As a result, metals not only have high melting points but are also known for their malleability and ductility at these elevated temperatures.

This characteristic is significant because it allows metals to maintain structural integrity and perform effectively in high-temperature applications, making them suitable for a wide range of industrial uses, such as in construction, manufacturing, and engineering components.
