In this assignment, you forget draw pretendings of four iotas based on their Lewis body structures, and answer 5 questions about each molecule you draw. Material Ideas * multicolored gumdrops, marshmallows, different soft candy (to make atoms in each model), fruit, aluminium foil, Styrofoam balls, cotton balls, play dough, cereal, balls, Q-tips, sensory hair pins, balloons, molecular model fit out, bodily structure written report * toothpicks (to introduce the covalent bonds in each model), paperclips or suffer 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, institution programs. enamour Web tools 2.0 or contact instructor for additive ideas. Introduction Chemists much use triple-dimensional models to help represent the geometry, or process of molecules. You can purchase a molecular cast equip at university stores or on the Internet, but in this body process you can make your own kit development the items listed above. In this assignment, you have several different options to demonstrate or show the geometry of your molecule.

One of the options was shown in the lesson. Procedure 1. spend a penny or draw the Lewis structure for each of the molecules listed below. H2O, NH3, CH4, CO2 2. confo rmation or draw a model of each of the Lewis! structures 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 employ between two atoms to represent a double bond, and one-third straight objects should be used between two atoms represent a triple bond.  c. Remember that the lone pairs on the...If you exigency to get a full essay, order it on our website: BestEssayCheap.com
