Why would a metal exist in a free state?

A. If it has enough mass to exist on its own
B. If it has valence electrons that make it highly reactive
C. If it doesn't easily combine with other elements
D. If it's a metal that's consistently used to make alloys

C. If it doesn't easily combine with other elements is the main reason why a metal can exist in a free state. If a metal has low reactivity, it will not easily combine with other elements, and therefore can exist in a pure form. However, options A, B, and D can also play a role in a metal existing in a free state. Some metals have a high enough mass to be found in nature on their own, while other metals are highly reactive and may be found in a free state as a result. Additionally, some metals are commonly used to make alloys, and can still be found in a free state.
