MAIN CONTENTS 2.1 Introduction 2.2 The Modern Periodic Table 2.3 Periodic properties in the Periodic Table 2.4 Advantages of periodic classification – Unit Summary – Review Exercises CHEMISTRY GRADE 9 Start-up Activity How can you use a table of repeating events to predict the next events? Table 2.1 shows a familiar table of repeating properties. What is it? Of course, it is a calendar, but it is a calendar with a difference – it is missing some information. You can determine what is missing and fill in the blanks. 1. Look at the calendar again. The calendar has columns of days, Sunday through Saturday. The calendar also has horizontal rows. They are its weeks. 2. Examine the information surrounding each empty spot. Can you tell what information is needed in each empty spot? 3. Fill in the missing information. For example: Conclude and Apply 1. One day in column 3 is marked X, and a day in column 4 is marked Y. What dates belong to these positions? Discuss your answers in your group. -

Unsolved Problems in Combinatorial Games
Games of No Chance 5 MSRI Publications Volume 70, 2017 Unsolved problems in combinatorial games RICHARD J. NOWAKOWSKI During the recent development of combinatorial game theory many more problems have been suggested than solved. Here is a collection of problems that many people have found interesting. Included is a discussion of recent developments in these areas. This collection was started by Richard Guy in 1991, and has been updated in each Games of No Chance volume. The problems are divided into five sections: A. Taking and breaking B. Pushing and placing pieces C. Playing with pencil and paper D. Disturbing and destroying E. Theory of games In the sections, the problems are identified by letters and numbers. Any number in parenthesis is the old number used in each of the lists of unsolved problems given on pp. 183–189 of AMS Proc. Sympos. Appl. Math. 43 (1991), called PSAM 43 below; on pp. 475–491 of Games of No Chance, hereafter referred to as GONC. Previous versions of the unsolved problems can also be found on pp. 457–473 of More Games of No Chance (MGONC); pp. 475–500 of Games of No Chance 3 (GONC3); and pp. 279–308 of Games of No Chance 4 (GONC4). Some problems have little more than the statement of the problem if there is nothing new to be added. References [#] are at the end of this article. Useful references for the rules and an introduction to many of the specific games mentioned below are: • M. Albert, R. J. Nowakowski, and D.

A Little About Silver Silver Is a Block D, Group 11, Period 5 Element
MicroCoat Technologies 1316 Somerset Drive McKinney, TX 75070 www.m-coat.com +1-972-678-4950 Fax +1-214-257-8890 Unparalleled in Polymer Coatings and Adhesives Technology TM A little about silver Silver is a Block D, Group 11, Period 5 element. The electronic configuration is [Kr]4d105s1. In its elemental form silver's CAS number is 7440-22-4. The silver atom has a radius of 144.5.pm and its Van der Waals radius is 144.pm. Silver has a brilliant white metallic luster. It is a little harder than gold and is very ductile and malleable, being exceeded only by gold and perhaps palladium. Pure silver has the highest electrical and thermal conductivity of all metals, and possesses the lowest contact resistance. It is stable in pure air and water, but tarnishes when exposed to ozone, hydrogen sulfide, or air containing sulfur. Silver nitrate has wide application in painting, xerography, chemical electroplating, in components for electric batteries and in medicine as catalyst. Silver chloride is another important compound, due to its ductility and malleability.
