Chemical Ionic Bonding POGIL

Document Content and Description Below

There are two major classes of compounds typically encountered as part of an introductory course: ionic and covalent compounds. The concepts describing how these compounds are held together can be de... veloped as you progress through your studies. However, before you get to those concepts you must be able to quickly classify a compound into one class or the other. In other words, your ability to classify compounds will guide how you will think about bigger ideas. The Model: Table 1 – Compounds that are considered… Reviewing the Model 1. The compound ZnCl2 is considered to be a (an) __________ionic____________ compound. 2. The compound that contains nitrogen and oxygen is a (an) ______covalent_________ compound. 2 Ionic Covalent ZnCl2 CCl4 Na2O P2O5 Fe2O3 N2O4 CuI NI3 uploaded by druidgrades Exploring the Model 3. Does the classification seem to be made based on how many atoms of each element are represented in the formula? 4. Write the symbols for the elements presented by the Model (Table 1) near their correct location on the outline of the periodic table. 5. Compare the types of elements found (metals or nonmetals) for the two classes of compounds. Do you see any trend in the type of elements present and the classification? no it doesn’t ionic is metal and nonmetal covalent is non metal, metal Exercising Your Knowledge 6.
