1、Periodic Table Study Guide5th Grade ScienceMrs. LaR 2008How to Draw Lewis StructuresLewis Structures1)Find your element on the periodic table.2)Determine the number of valence electrons.3)This is how many electrons you will draw.Lewis StructuresFind out which group (column) your element is in.This w
2、ill tell you the number of valence electrons your element has.You will only draw the valence Groups - ReviewEach column is called a “group”Each element in a group has the same number of electrons in their outer orbital, also known as “shells”.Group 1 = 1 electronGroup 2 = 2 electronsGroup 8 = 8 ele
3、ctronsExcept for He, it has 2 electronsThe electrons in the outer shell are called “valence electrons” 3 3, , 4 4, , 5 5, , 6 6, , 7 7 Lewis Structures1)Write the element symbol.2)Carbon is in the 4th group, so it has 4 valence electrons.3)Starting at the right, draw 4 electrons, or dots, counter-cl
4、ockwise around the element symbol.Lewis Structures1)Check your work.2)Using your periodic table, check that Carbon is in the 4th group.3)You should have 4 total electrons, or dots, drawn in for Carbon.Lewis StructuresOn your worksheet, try these elements on your own:a)Hb)Pc)Cad)Are)Clf)AlLewis Struc
