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

Lecture 2 (Chapter 4 & 25) Atomic Structure Democritus (400 BC) ? Postulated there must be some basic unit of matter that could not be divided any further. ? Basic unit ? atomos (Greek = indivisible) Dalton Dalton?s Atomic Theory ? All matter is composed of extremely small particles called atoms ? All atoms of a given element are identical having the ame size, mass and chemical properties. Atoms of a specific element are different from those of any other element ? Different atoms combined in simple whole number ratios to form compounds ? Ina chemical reaction, atoms are separated, combined, or rearranged ? Atoms cannot be created, divided into smaller particles or destroyed. Scientist and Experiments Cathode Ray Tube Experiments ? Plum pudding model ?

The Chemical Context of Life 8/22/13 6:23 PM Chapter 1: Exploring Life Biology?s Most Exciting Era Biology- the scientific study of life Biologists explore life from the microscopic to the global scale A Hierarchy of Biological Organization The biosphere- consists of all the environments on Earth that are inhabited by life. Ecosystems- consists of all the living things in a particular area, along with all the nonliving components of the environment with which life interacts. Ex. forest The biosphere is composed of ecosystems Communities- the entire array of organisms inhabiting a particular ecosystem. The set of populations that inhabit a particular area Populations- consists of all the individuals of a species (forms of life) living within the bounds of a specified area

Chapter 7 ? Periodic Properties of the Elements 7.1 Development of the Periodic Table ? Majority of elements discovered 1735-1843 ? Elements arranged to reflect trends in chemical and physical properties ? Periodic table arose from periodic patterns in electronic configurations o Valence orbitals o Trends in rows and columns ? Mendeleev and Meyer ? Modern periodic table 7.2 Effective Nuclear Charge Effective nuclear charge (Zeff) is the charge experienced by an electron on a many-electron atom. The effective nuclear charge is not the same as the charge on the nucleus because of the effect of the inner electrons. ? The electron is attracted to the nucleus, but repelled by electrons that shield or screen it from the full nuclear charge.
