Heat and Temperature. Let’s Review. According to the kinetic theory of matter , all matter is made up of tiny particles – called atoms or molecules. . - These particles are always moving, and it is this movement that helps decide what state of matter exists (solid, liquid, gas, plasma).By angus

ATOMS, ENERGY, & LIGHT. THE QUANTUM MECHANICAL MODEL of the ATOM Created by P. Perkerson. Atomic Models. What was Dalton’s model of the atom like? Thomson’s? Rutherford’s? What is the significance of the proton? What is the significance of the electron?
Mater, Energy, Elements, and Atoms. By: Mark, Noah, and Katie. Definitions. Matter- Anything that occupies soace and has mass Energy- the ability to do work Elements- any of the building blocks of matter, oxygen, hydrogen, carbon, for example
3.4 Energy levels in atoms. Electrons in atoms. Electrons are attracted to a positive nucleus by electrostatic force. Electrons move about in allowed orbits or shells with different energy levels. The lowest energy state of an atom is called its ground state.
Binding energy in atoms and nuclei. [Sec. 4.1 Dunlap]. CONCEPT OF BINDING ENERGY. The binding energy of an atom is the energy released as all the constituent particles (n, p and e) come together FROM INFINITY under both the STRONG force and the EM force.
How do we get energy from atoms?. Atoms contain huge amounts of energy, and there are two ways in which this energy can be released. nucleus. One way is to split atomic nuclei in a process called nuclear fission . Another way is to join nuclei together in a process called nuclear fusion .
Atoms!. Lynn A. Melton University of Texas at Dallas Mini-CAST February 21, 2009. Website. http://www.chemchapterzero.com Lots of ideas there. It you use this material in the classroom, it may take you a month or more to work through the material.. The “hands on” stuff will count as labs.
