1. Mineral in the earth's crust exists naturally in form of solid elements or compounds * True
False​

True

Explanation:

Minerals can be defined as any form of naturally occurring, inorganic solid substance characterized by a crystal structure. Also, minerals are homogeneous in nature with a defined chemical composition and characterized by a crystal structure comprising of ions, atoms, or molecules in an orderly arrangement.

Generally, molecules attach on the inside of a mineral to give it shape. Therefore, the molecule of a mineral is a crystal three-dimensional regular structure (arrangement) of chemical particles that are bonded together and determines its shape.

Furthermore, the chemical composition (property) of a mineral reflect the presence and arrangement of atoms in each.

Due to the fact that these molecules are structurally arranged (ordered) and are repeated by different symmetrical and translational operations, they determine the shape of minerals. Some examples of minerals are iron, copper, aluminum, tin, coal, quartz, feldspar, mica, etc.

Additionally, inorganic-crystalline solid substances which are found naturally within earth are referred to as minerals.

In conclusion, a mineral in the earth's crust exists naturally in form of solid elements or compounds.
