Draw the orbital diagrams of the following compounds LiF KF NaCI MgO Li O Na S BeF What is the hydrogen bond How does the strength of this bond compare with the strengths of ionic and covalent bonds What common inorganic molecule forms hydrogen bonds with itself Diagram how the hydrogen bonds are formed among these molecules What is an ion What is a cation Give two examples What is an anion Give two examples Why is the hydrogen ion often called a proton Molecular model kits are available in the laboratory to build models of the atomic structures of covalently bonded molecules Each colored ball represents an atom and the hours in the atom represent covalent bonding sites For example a black ball represents an atom of carbon Carbon needs four electrons in its outermost shell to reach stability Thus the carbon atom black ball has four holes for four covalent bonding sites Construct models of the following inorganic molecules using the molecular model kit Refer to your text for help When you are finished building each molecule have the instructor initial below and then draw the orbital and structural diagrams of the model in the space provided Do not attempt to draw the molecule without having first made a model of it If you have difficulty please ask your instructor for help 1 H 2 H O 3 NH 4 CH 5 0 6 CO Explain why CO and CH are not considered organic List and briefly explain the unique properties of water in terms of its importance to living systems Explain why water is polar molecule
