Definition |
Metals are substances that are hard and have high tensile strength. |
Non-metals are substances that are generally gases and not hard. |

Difference between Metals and Non-Metals
Elements are chemically occurring natural substances that may be found in a free state or combined state. They are extracted from ores. ores are found deep inside the earthâs crust. The ores from which metals can be easily extracted are called minerals. By the definition of minerals, metals can be extracted.
Based on their characteristics, elements are categorised as either metals or nonmetals. Much of the time, you can determine if an element is a metal by its metallic sheen, but this isnât the sole distinction between these two broad categories of elements.
