X-Ray Physics. Assumptions: Matter is composed of discrete particles (i.e. electrons, nucleus) Distance between particles >> particle size X-ray photons are small particles Interact with body in binomial process Pass through body with probability p

Formation of Mercury. By Triana Henz. In the beginning…. There was a giant cloud of particles within the Milky Way Particles start to rotate The cloud starts to collapse on itself A star is born at the center!!. What takes place in a few Myr?. Accretion Theory takes place

Metallic Bonding. Strong forces of attraction are responsible for the high melting point of most metals. CA Standards. Students know atoms combine to form molecules by sharing electrons to form covalent or metallic bonds or by exchanging electrons to form ionic bonds. . Metallic Bonding.

POLYPROPYLENE!. One Popular Polymer!. What’s so great about POLYPROPYLENE?. High Melting Point (dishwasher safe!) Intermediate crystallinity: tough without being brittle High resistance to fatigue (living hinge) Chemically Inert CHEAP to MAKE!!!. Polypropylene comes from Propylene!.

Chapter 8 Molecular Shape. The shape of a molecule can be important in determining its chemical reactions Molecular shape is often very important in the chemistry of living things. Molecular geometry also helps determine the polarity of molecules.

Sputter Materials. Lecture 10 G.J. Mankey gmankey@mint.ua.edu. The Key System. The Key system has a stainless steel bell jar, a cryopump, gas supply system, four 2" targets and a substrate holder for six substrates.

The Periodic Table of Elements. Elements. Science has come along way since Aristotle’s theory of Air , Water , Fire , and Earth . Scientists have identified 92 Natural elements , and created about 28 others. Elements.

Properties of Polymers. Different polymers have different properties. Properties can depend on how the polymer is made. Learning Outcomes. All are able to state that monomers used to make plastics will affect the properties.

Intermolecular Forces and Liquids and Solids. Chapter 11. A phase is a homogeneous part of the system in contact with other parts of the system but separated from them by a well-defined boundary. 2 Phases. Solid phase - ice. Liquid phase - water. 11.1.
