2 Drill # /22/14Use the periodic table to answer the following questions.Name, period, and group of element #88? _________, ___, ____Element name , symbol, and atomic # in group 6A (or 16) and period 3?__________, _____, _____4. Element name , symbol, and atomic # in group 8A (or 18) and period 1?
3 Topic: Organizing the Elements Objective: SWBATExplain how the periodic table is organizedIdentify the main blocks in the periodic tableHW: Draw a labeled diagram of the periodic table.Don’t include specific elements but do include periods, groups, and the main blocks
5 The Modern Periodic Table The Periodic Table is a listing of all the known elements.The elements are organized by:Atomic numberChemical Properties
6 Who created it? First some individual elements were discovered. By 1860 about 60 elements were known. In 1869, Russian chemist Dimitri Mendeleev proposed arranging elements by atomic weights and properties.The table contained gaps but Mendeleev predicted the discovery of new elements.
11 Periods = RowsThe bottom two rows actually fit in the gap shown in periods 6 and 7They are pulled out so that the periodic table is shorter
12 GP: Filling in the Periodic Table We will cut a blank periodic table and reassemble it as it should be (stretch it)Next, we will fill out the atomic numbers in proper orderMaterials:Blank tableScissorsLong paperTape or gluePencil
13 Now cut out the extra margins and glue the table in the long paper
15 Number all boxes in the following order: Start at the top left = 1Skip over to finish the first period on the right = 2Start a new period on the next line…keep going in order…Write in pencil that can be erased and don’t press too hard !!
16 Color and label the main blocks page 163 Include a color code key Choose your own colors
18 Did we achieve? Objective: SWBAT Explain how the periodic table is organizedIdentify the main blocks in the periodic tableHW: Draw a labeled diagram of the periodic table.Don’t include specific elements but do include periods, groups, and the main blocks
19 ET: To get credit you must work quietly in your seat and answer in complete sentences How many periods are in the periodic table?What period are the lanthanides in?Why do we list the lanthanides and actinides under the main table?
20 Groups = Columns (called Families) The elements in a group have the same number of electrons in their outer orbital.Every element in the first column (group one) has one electron in its outer shell. Every element on the second column (group two) has two electrons in the outer shell. As you keep counting the columns, you'll know how many electrons are in the outer shell.There are some exceptions to the order when you look at the transition elements, but you get the general idea.
