CALIFORNIA STANDARDS TEST CHEMISTRY (Blueprint adopted by the State Board of Education 10/2002) CALIFORNIA CONTENT STANDARDS: CHEMISTRY # of Items % Atomic and Molecular Structure 6 10.0% 1. The periodic table displays the elements in increasing atomic number and shows how periodicity of the physical and chemical properties of the elements relates to atomic structure. As a basis for understanding this concept: a. Students know how to relate the position of an element in the periodic table to its atomic number and atomic mass. 1 b. Students know how to use the periodic table to identify metals, semimetals, non-metals, and halogens. 1

Daniel Seo 10/10/13 Period 5 Chapter 6 Thermochemistry Outline 6.1 The Nature of Energy 1. Energy ? capacity to do work (or to produce heat) i. Work ? force acting over a distance (moving an object) ii. Heat ? form of energy. ? chemicals may store potential energy in their bonds that can be released as heat energy 2. The law of conservation of mass ? energy can be converted from one form to another, but cannot be created or destroyed ? is also the first law of thermodynamics. i. Potential energy ? energy due to position or composition ii. Kinetic energy ? energy due to the motion of an object ? K? = 1/2mv2 3. Temperature reflects random motion of particles in a substance 4. Temperature indicates the direction in which heat energy will flow

Periodic Table Worksheet Name Per. 1. Periodic means . Examples of periodic properties: 2. What is a group (or family)? What is a period? 3. How can you determine the number of electrons in an element?s outer energy level by the group it?s in? 4. What is the octet rule? 5. Why do elements that make positive ions occur on the left side of the periodic table while those that make negative ions occur on the right? 6. What is the common name for group 18? Why do the elements of this group usually not form ions? 7. Complete the following table. Group Common Name Charge on Ions of this Group 1 2 13 / 3A -------- 16 / 6A -------- 17 / 7A 8.

Warm-Up Your car's gas tank holds 18.6 gallons and is one quarter full. Your car gets 16 miles/gal. You see a sign saying, "Next gas 73 miles." Your often-wrong brother, who is driving, is sure you'll make it without running out of gas. You're not so sure and do some quick figuring: Matter and Change Matter: Anything that has mass and takes up space. Mass: measure of the amount of matter. Matter and Change Atoms: Smallest unit of an element that maintains the properties of that element Elements: pure substance made of one atom. Compounds: made of atoms of two or more elements that are chemically bonded Physical properties and changes Physical properties: quality or condition of a substance that can be observed or measured without changing the substance
