12/23/2023 0 Comments Ion bonding formula![]() In an ionic bond, electrons are localized to one of the atoms (giving it an overall negative charge), while the other atom has an overall positive charge. These can be evenly shared (covalent bond) or unevenly shared (polar covalent bond). In a covalent compound, valence electrons are shared between the two atoms in the bond. Table 1: Classification of Compounds Covalent Compounds ![]() In this part of the worksheet, you will learn to easily classify compounds into one of the two categories. The classification of a compound depends on the type of chemical bond between the elements in the compound. II: Exercises Part A: Covalent or Ionic Compound? Many compounds, especially those discussed in general chemistry courses, are classified as either covalent compounds or ionic compounds. You will need to spend some time with this material, as the formal rules of nomenclature may not be presented in lecture, although they will certainly be used in discussions of Lewis structures and reaction chemistry. Your textbook has tables of the names and formulas of common cations and anions, and discusses the rules of nomenclature in detail. This exercise is just the beginning of the work needed to be done to master the rules of writing formulas and nomenclature. In this exercise, you will evaluate some representative models to develop the rules used to classify a compound, to predict the formula of a compound, and to name the compound. ![]() The behavior of matter depends on the type of elements that are present and on the structure of those elements-how they are connected to make a molecule. I: Background Chemistry deals with matter, and there is a tremendous variety of matter in the universe. By the end of the lab you should be able to name the compounds you will encounter in general chemistry, as well as write the chemical formula if given a name. In this lab you will learn the rules behind naming chemical compounds, both ionic and covalent.
