Question

Why molecules of minerals are crystalline in shape

Answer 1

The atoms in a mineral are arranged in an organised 'atomic structure'. They connect together to form molecules, and the molecules stack together in a regular pattern to form a crystal. The shape of a crystal depends on the way the molecules are stacked up inside it.

Answer 2

Answer:

Minerals are made from elements which are already in hard state under the earth's crust and when atoms of different elements came to form mineral,it takes crystalline structure.
