Question

Quizplus · Accepted Answer

Minerals are naturally occurring substances that are solid and have a defined chemical composition, which is usually a compound or a mixture of compounds. However, these compounds are composed of specific elements in fixed ratios. Therefore, option A is correct, as minerals are composed of elements. Option B is incorrect because minerals can be either compounds or mixtures of compounds. Option C is incorrect because there are minerals composed of only one element, such as sulfur and diamond. Option D is incorrect because the chemical composition of a mineral largely determines its physical and chemical properties, such as its hardness, color, and crystal structure.
