Covalent Bonding . Draw electron dot diagrams for the following atoms: Ca, B, C, S, and Br. Where is a “molecular orbital” located specifically? What actually causes the attraction between atoms in a covalent bond? What type of bonding occurs between metals and non-metals? What type of bonding occurs between non-metal atoms? AP CHEMISTRY CHAPTER REVIEW CHAPTER 7: COVALENT BONDING You should understand the nature of the covalent bond. You should be able to draw the Lewis electron-dot structure for any atom, molecule, or polyatomic ion.

Ionic bonds result from the transfer of electrons from one atom to another; Covalent bonds result from two atoms sharing electrons. 2) Describe the relationship between the length of a bond and the strength of that bond. Use delta notation ( and –) to indicate which atom is more electronegative, and ii. Use an arrow to point from the less electronegative atom to the more electronegative atom. C—Cl N—O H—O 6. Identify the type of bond described for each of the following as ionic, polar covalent, nonpolar covalent, or metallic. Chemical Bonding Worksheet #2 (Types of Bonds) 1.
