**Periodic Table Study Guide**How to Draw Lewis Dot Structures 8th Grade Science**Lewis Dot Structures**• Find your element on the periodic table. • Determine the number of valence electrons. • This is how many electrons you will draw.**Lewis Dot Structures**• Find out which group (column) your element is in. • This will tell you the number of valence electrons your element has. • You will only draw the valence electrons. www.chem4kids.com**Groups**Group 18 = 8 Electrons Group 1 = 1 electron Except for He, it has 2 electrons Group 2 = 2 electrons • Each column is called a “group” 1314151617 • Each element in a group has the same number of electrons in their outer orbital, also known as “shells”. • The electrons in the outer shell are called “valence electrons” www.chem4kids.com**Lewis Dot Structures**• Write the element symbol. • Carbon is in the 14th group, so it has 4 valence electrons. • Starting at the right, draw 4 electrons, or dots, counter-clockwise around the element symbol. C**Lewis Structures**• Check your work. • Using your periodic table, check that Carbon is in the 14th group. • You should have 4 total electrons, or dots, drawn in for Carbon.
