Understanding Covalent Bonds: Formation and Electron-Dot Diagrams

This lesson focuses on covalent bonds, where valence electrons are shared between atoms to form molecules. Students will learn to explain the concept of covalent bonding and practice drawing electron-dot diagrams for simple molecules. The lesson covers diatomic molecules made up of the same element, such as nitrogen, oxygen, hydrogen, chlorine, bromine, iodine, and others. By the end, students will be capable of visualizing covalent bonds through diagramming methods. Homework will include completing electron-dot worksheets and answering review questions.

Presentation Transcript

  1. Physical ScienceUnit 1 Chapter 5 Lesson 3 Covalent Bonds

  2. Start Up • Objectives: • Explain covalent bonds • Write electron-dot diagrams for simple molecules • Answer the following question: • How are molecules formed?

  3. Covalent Bonds • A bond where valence electrons are shared between atoms • Enables atoms to form molecules

  4. Diatomic Molecule • A molecule made up of two atoms of the same element • Electrons are shared equally • Only elements can have diatomic molecules: • Nitrogen • Oxygen • Hydrogen • Chlorine • Bromine • Iodine • Flouride

  5. Hard to See! • Covalent bonds are hard to visualize, so scientists came up with a diagramming method to show these bonds • Called electron-dot diagram • A model in which the chemical symbol represents the nucleus and all the filled inner energy levels of the atom and one dot represents each valence electron

  6. Let’s Do it! • Let’s do some electron dot diagrams together

  7. Homework • Complete electron-dot ws in packet • Answer review questions
