5 Questions
Which of the following best describes a mineral?
A naturally occurring solid with a highly ordered atomic arrangement
What does it mean for a mineral to have a definite (but not generally fixed) chemical composition?
The chemical composition of a mineral can change over time
What is the significance of a mineral having an ordered internal structure?
It means that the atoms in a mineral are arranged in a specific pattern
What does it mean for a mineral to be naturally occurring?
It means that minerals are formed through inorganic processes

It refers to the formation of minerals from organic processes
Study Notes
Characteristics of Minerals
- A mineral is a naturally occurring inorganic solid substance with a specific chemical composition and a crystalline structure.
- A mineral has a definite chemical composition, but it can vary slightly due to the presence of impurities or substitutions of elements.
- The ordered internal structure of a mineral refers to its crystalline arrangement, which is repeating and predictable, giving the mineral its unique properties.
- A mineral must be naturally occurring, meaning it is formed through geological processes, rather than being created artificially.
- In the context of minerals, an inorganic process is a natural process that does not involve living organisms, such as the formation of rocks through plate tectonics or the cooling of magma.
