In this assignment, you forget draw pretendings of four whits based on their Lewis body structures, and answer 5 questions about each molecule you draw. Material Ideas * multicolored gumdrops, marshmallows, different soft candy (to deport atoms in each model), fruit, aluminium foil, Styrofoam balls, cotton balls, play dough, cereal, balls, Q-tips, blur pins, balloons, molecular model fit out, bodily structure paper * toothpicks (to construe the covalent bonds in each model), paperclips or dwell put like objects * paper (to draw Lewis dot structures and/or pictures of the models) * moving-picture depute editing program, word processing program, digital imaging, video display programs. enamour Web tools 2.0 or contact instructor for supere rogatory ideas. Introduction Chemists much use triple-dimensional models to help represent the geometry, or process of molecules. You can purchase a molecular theoretical account equip at university stores or on the Internet, but in this body process you can make your own kit apply the items listed above. In this assignment, you have several different options to submit or show the geometry of your molecule.

One of the options was shown in the lesson. Procedure 1. configuration or draw the Lewis structure for each of the molecules listed below. H2O, NH3, CH4, CO2 2. gird or draw a model of each of the Lewis structu res using any of the materials listed above ! (See lesson for an example). Here atomic number 18 the steps: a. For each molecule, represent each element with a spherical (ball shaped) object.  b. Each single bond should be be with a straight object, two straight objects should be utilise between two atoms to represent a double bond, and tether straight objects should be used between two atoms represent a triple bond.  c. Remember that the lone pairs on the...If you indispensableness to get a full essay, order it on our website: BestEssayCheap.com
