Every mineral has a strict chemical formula. Although, practically the atoms or ions are not positioned perfectly to give the formula, hence they exist as mixtures.

Mechanical weathering is the physical breakdown of rocks into smaller pieces without changing their chemical composition, such as through frost wedging or abrasion. Chemical weathering involves the alteration of rock material through chemical reactions, leading to the formation of new minerals and compounds, such as through processes like oxidation or hydrolysis.
The composition of a rock is decided by the % of the constituent minerals and components contained inside it. The minerals that form up rocks have outlined chemical compositions and rigid atomic structures. once daylight strikes the rock's surface, the composition and atomic structure of the various minerals
Chemical weathering changes the mineral composition of rocks by altering the chemical composition of minerals through processes like hydration, oxidation, and dissolution. This can result in the breakdown of minerals and the formation of new minerals.
Minerals are solid homogeneous inorganic substances having a specific chemical composition that can be represented by a chemical formula. They are different from rocks, which can be a mixture of minerals and non-minerals and do not have a specific chemical composition.

Minerals (other than elemental minerals) are combinations of elements.
The first is that minerals are natural, made without human intervention. Second, minerals are solid. Third, minerals are inorganic. Fourth, minerals are crystalline in composition.
These minerals are oxides.
Minerals are classified according to their composition
