Determine what factors determine the type of bond formed between atoms in a molecule or formula unit. Indicate how it is measured and the electronegativity increases or decreases as the elements move up and down a group or across a period. Discuss the ionic and covalent characteristics of molecules.
Using a series of examples, determine how to classify molecules as either ionic, pure nonpolar covalent, polar covalent and dipolar. Practice problems using the subtraction of electronegativity values to determine which class they fall into.
