Unformatted text preview: Michael Patino 01115539 Chem 1122-Trupta Experiment 10- Chemical Bonds, Molecular Models, and Molecular Shapes Objective / Aim of the lab- The objective of this lab is to allow the experimenter to directly relate to the ways in which atoms are bonded together into molecules. In this experiment, my partners and I had to construct simple ball-and-stick models to form some common molecules also known as a Lewis structure. This allowed us to understand the electron arrangements in molecules, and the resulting shapes of the molecules. Introduction/background information- The models constructed serve as a three-dimensional representation of an abstract idea. The chemical bonds that hold atoms together in molecules consist of pairs of electrons shared between two atoms. The octet rule is when atoms tend to share outer electrons in that the union has a share in an octet (8) of electrons in its outermost shell. In the periodic table, the location of each element provides information about the number of electrons in the outermost level of the...
