In amorphous solids , the atoms or molecules are held together in a completely random formation. A friend in your chemistry class is struggling to understand why crystalline solids are grouped into four main types: network, molecular, ionic, and metallic. Which explanation below will BEST help him begin to understand why chemists might have these groups? Solids have many different properties. It is possible to tell the difference between a solid with a crystalline structure and one with an amorphous structure just by looking at it. An engineer is designing an electrical system and is looking for a material to transmit energy. She has four solids available, each made with different materials.
Labor Day Schools and Offices Closed. A warm welcome to all new and returning students and families for the school year! Over of these are new Raptors, and include the return of foreign exchange students with a young man from Sweden Hurrah! Summer Scholars August was an unqualified success as we hosted nearly all of the entering freshmen. Student mentors and volunteers, as well as teachers and staff, ensured that this week was both fun and informational. Thank you! Scores went up in all areas from our initial assessments in the fall of
There are five main types of solids, each of which has its own properties and structures. Let's have a look. As we discussed at great length in Ionic Compounds , ionic solids consist of cations and anions held together by the strength of their opposite charges.

Not all solids are the same. Solid substances have a tremendously wide range of melting points. Some are conductive, others are not. Some readily dissolve in water, others do not. List the four types of solids illustrated in Model 1.
A solid is like a liquid in that particles are in contact with each other. Solids are unlike liquids in that the intermolecular forces are strong enough to hold the particles in place. The solid phase has several characteristics. First, solids maintain their shape. They do not fill their entire containers like gases do, and they do not adopt the shape of their containers like liquids do. They cannot be easily compressed like gases can, and they have relatively high densities.

As you should remember from the kinetic molecular theory, the molecules in solids are not moving in the same manner as those in liquids or gases. Solid molecules simply vibrate and rotate in place rather than move about.
