PPT-Nonmetal Gases

Noble gases and diatomic elements except bromine and iodine These all have only London dispersion forces These are very weak intermolecular forces They all have very low melting points obviously since they are gases. Chapter 5. E-mail: . benzene4president@gmail.com. Web-site: http://clas.sa.ucsb.edu/staff/terri/. Gases – Ch. 5. 1. Draw the following:. a. A closed monometer attached to a flask filled with CO at 250 . The Periodic Table of Elements. Foundations of Science. Atomic Structure Review. Protons determine what ______________ an atom is. Electrons determine the characteristics of an atom. Atomic Structure Review. Chemistry—2. nd. semester. Properties. All gases share some physical properties:. Pressure (P). Volume (V). Temperature (T). Number of moles (n). These properties combine to describe the behavior of gases using the “gas laws”. Vocabulary:. Demitri. Mendeleev. relative atomic mass. periodicity. atomic number. periodic law. family/group. Alkali . Metals. Alkali Earth Metals. Transition Metals. Halogens. Noble Gases. Inner Transition Metals. Molecular Compounds: . Sharing Electrons. The names of molecular compounds need prefixes because several different compounds can be formed from the same two nonmetals. .. Learning Goal . Given the formula of a molecular compound, write its correct name; given the name of a molecular compound, write its formula.. The Kinetic-Molecular Theory of Matter. Gases. Behavior of Atoms. Kinetic-molecular theory. .  . based on the idea that particles of matter are always in motion. Can be used to explain the properties of solids, liquids, and gases in terms of the energy of the atoms and the forces that act between them. Partial Pressure, . Gases in Chemical . Reactions . & KMT. Partial Pressures of Gases in Mixtures. Each gas, in a mixture of gases. , exerts . a specific amount of pressure. This pressure can be calculated using the ideal gas law:. Behavior of Gases Chapter 3.2 Behavior of Gases What behaviors do gases display? Do they behave the same all the time? What variables are involved with gas behavior? Variables Pressure – the amount of collisions between gas particles and walls of the container (balloon). Measured in kilopascals ( Particle Theory. All . matter consists of many, very small particles . The particles . are constantly moving or in a continual state of motion. . The . degree to which the particles move is determined by the amount of energy they have and their relationship to other particles. . The particles are far apart.. The particles move very fast.. The particles have no attraction nor repulsion for each other.. The fact that they have no definite shape or volume – they take the shape of the container.. Kinetic Molecular Theory of Gases. This is the six point model that is used to explain the behavior of gases. Points of the Kinetic Molecular Theory. 1. Gases are composed of atoms or molecules that have mass. SmartStarter. What is the octet rule?. SmartStarter. Draw the electron dot diagram for ionic compound MgCl. 2. Compare. – Eyes on Chemistry. Epsom Salts. Rock Salt. Sucrose. One more…. WHAT DO YOU NOTICE ABOUT THEIR STRUCTURE?. A strong attraction to each other and a large volume . A strong attraction to each other and no volume . A weak attraction to each other and a large volume . A weak attraction to each other and no volume . Sharing Electrons. The names of molecular compounds need prefixes because several different compounds can be formed from the same two nonmetals. .. Learning Goal . Given the formula of a molecular compound, write its correct name; given the name of a molecular compound, write its formula..
