Understanding Lewis Structures and Valence Electrons in the Periodic Table

This study guide explains how to draw Lewis structures and understand atomic bonding using the periodic table. Start by identifying the group number of an element, which indicates the number of valence electrons. For example, carbon in Group 4 has 4 valence electrons. Learn to visualize these electrons as dots around the element symbol, following a counter-clockwise pattern. Practice with various elements such as Hydrogen, Phosphorus, Calcium, Argon, Chlorine, and Aluminum. Additionally, this guide addresses finding the number of protons, neutrons, and electrons for any given element.

Presentation Transcript

  1. Periodic Table Study Guide How to Draw Lewis Structures An explanation of how atoms can bond to each other

  2. Lewis Structures • Find the element on the periodic table. • Determine the number of valence (extra) electrons based off the group number.

  3. Lewis Structures • Find out which group number (column) your element is in. • This will tell you the number of valence (extra) electrons your element has. • You draw only the valence electrons.

  4. Groups - Review Group 8 = 8 electrons Group 1 = 1 electron Except for He, it has 2 electrons Group 2 = 2 electrons • Each column is called a “group” 3,4,5,6,7 • 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”

  5. Lewis Structures • Write the element symbol. • Carbon is in the 4th group, so it has 4 valence electrons. • Starting at the right, draw 4 electrons, or dots, counter-clockwise around the element symbol. C

  6. Lewis Structures • Check your work. • Using your periodic table, check that Carbon is in the 4th group. • You should have 4 total electrons, or dots, drawn in for Carbon. C
