Amorphous and crystalline are the two types of matter classified by the arrangement of its atoms.
Explanation:
There are several criteria present to classify the matters present in this universe. We can classify the matter based on their physical state like solid, liquid and gas. We can also classify the matter based on their composition like pure substance and mixtures. Similarly another way of classifying the matter is based on their arrangement of atoms. If the atoms are arranged in an orderly manner, then they are termed as crystalline matter. And if the atoms are arranged in a random way, then they are termed as amorphous matter.
Thus, the two types of matter classified by the arrangement of its atoms are amorphous and crystalline.
Because of their atom's composition. some are naturally packed closer together and stronger and more durable, while others tend to be more loose and breakable and/or weaker/less durable. also with how their atoms are composed is how the atoms interact with each other/ how they share or give or take electrons.
