(Glencoe chapter #4, 6, 7)
Objectives in bold have already been taught; objectives in italics have not been taught yet. List at bottom is those objectives we did not have time to study.
8. Knows that matter is made up of tiny particles called atoms, and different arrangements of atoms into groups compose all substances
8.1 Understands the “Particle model of Matter”
8.2 Can compare and contrast to “Dalton’s Atomic Theory”
8.D Understands the subatomic particles makeup of every atom including name, charge, location and relative mass of protons, neutrons and electrons
8.D.1 Explain a brief history of scientists and their atomic contributions such as Aristotle, Democritus, Dalton, Thompson, Rutherford, Bohr and Mendeleyev and Lewis.
8.D.2 Be able to solve for name, Standard Atomic Notation, number of protons, neutrons and electrons for first 20 elements
8.2 Understands how elements are arranged in the periodic table, and how this arrangement shows repeating patterns among elements with similar properties (e.g. numbers of protons, neutrons, and electrons; relation between atomic number and atomic mass) [Describe and explain the Periodic Table as a method of classifying elements and its use in predicting properties of elements]
8.2.1 Be able to draw Bohr-Rutherford diagrams for the first 20 elements and explain increase in number of rings/orbits /shells with each row/period and same number of valence electrons in each column/family (did with D, not F)
8.2.2 Describe the build up of electrons in shells and understand the significance of the noble gas electronic structure and of valence electrons for the first 20 elements explaining octet and duet rules
8.2.4 Give properties of 5 major families of the periodic table: Hydrogen, Alkali Metals, Alkaline earth Metals, Halogens, and Nobel gases
(OBJECTIVES we did not study in 2007/2008)
8.2.3 Classify the Periodic Table by a) metals and non-metals (teach staircase method) b) transitional, inner transitional and representative elements
8.2.5 Define Isotopes and be able to make simple calculations for average atomic mass
8.2.6 Describe the change from metallic to nonmetallic character across a period (i.e. Cu à Br)
8.2.7 Describe lithium, sodium and potassium in Group 1 as a collection of relatively soft metals showing a trend in melting point, density and in reaction with water
