Explain the difference between a pure substance and a mixture.
Hey guys, in this question were asked to tell the difference between a crystalline solid and an amorphous solid, now basically it's all based on the arrangement of atoms that's how we're able to tell the difference between these two types of solids, now within a crystalline solid atom are highly organized, OK? So they take on a particular arrangement so they align in a certain way and it's consistent throughout the entire solid so let's say they decide to connect in pairs of 4 before they branch out and connect to another group this is consistent to be entire solid this helps to increase the durability and strength of the solid as well, a great example of a crystalline solid would be diamond, diamond is one of the strongest naturally occurring minerals in our environment and the reason for that is because it takes on a crystalline solid form the atoms of the carbon which make up diamond arrange themselves in the same exact arrangement throughout the entire diamond on solid. Now in an amorphous solid atoms are not highly organized so they're kind of random in one portion of the solid they arrange in a certain way and as you move throughout the solid the arrangement or order changes randomly so it's not as highly organized, here this results in a solid that is not as durable and not as strong, great examples of a amorphous solid you have plastic or glass you would think Glass is a hard substance therefore must be crystalline solid but no glass is really easy to break drop glasses I'm sure we've actually all done this break a mirror glass is very fragile mainly because the atoms are not dispersed evenly and in an organized manner throughout the solid, so remember crystalline solids highly organized, very strong. Amorphous solid not as highly organized much more brittle easier to break.
