Pre-Activity Quiz Answer Key (Pdf)
Name: ____________________________________________ Date: ___________________ Class: ________________________ Pre-Activity Quiz Answer Key 1. Consider a molecule of carbon monoxide (C O): A. Do you think the electrons in the triple bond pull closer to the C atom or the O atom, or are they equally shared? Use the concept of electronegativity to explain your response. Answer: They are closer to the O atom. Using the electronegativity scale from a textbook, the result is a polar covalent bond shifted towards the O atom. B. Is the bond polar or non-polar? Polar 2. In today’s engineering challenge, you will sketch out Lewis dot diagrams for various molecules and polyatomic ions. Then you will construct each molecule using a molecular model kit. The kits contain three different representations: colored balls, short sticks and long flexible springs. A. Each colored ball corresponds to a different atom. How can you determine which color to use for each atom? Use the reference sheet that comes with the kit. B. For what bond type do you think the short sticks are used? Covalent bonds C. If you were to build a triple bond, what would you use to represent a triple bond and how many would you use? Use springs, three springs 3.

A Web-Based 3D Molecular Structure Editor and Visualizer Platform
Mohebifar and Sajadi J Cheminform (2015) 7:56 DOI 10.1186/s13321-015-0101-7 SOFTWARE Open Access Chemozart: a web‑based 3D molecular structure editor and visualizer platform Mohamad Mohebifar* and Fatemehsadat Sajadi Abstract Background: Chemozart is a 3D Molecule editor and visualizer built on top of native web components. It offers an easy to access service, user-friendly graphical interface and modular design. It is a client centric web application which communicates with the server via a representational state transfer style web service. Both client-side and server-side application are written in JavaScript. A combination of JavaScript and HTML is used to draw three-dimen- sional structures of molecules. Results: With the help of WebGL, three-dimensional visualization tool is provided. Using CSS3 and HTML5, a user- friendly interface is composed. More than 30 packages are used to compose this application which adds enough flex- ibility to it to be extended. Molecule structures can be drawn on all types of platforms and is compatible with mobile devices. No installation is required in order to use this application and it can be accessed through the internet. This application can be extended on both server-side and client-side by implementing modules in JavaScript. Molecular compounds are drawn on the HTML5 Canvas element using WebGL context. Conclusions: Chemozart is a chemical platform which is powerful, flexible, and easy to access. It provides an online web-based tool used for chemical visualization along with result oriented optimization for cloud based API (applica- tion programming interface). JavaScript libraries which allow creation of web pages containing interactive three- dimensional molecular structures has also been made available. -
Getting Started in Jmol
Getting Started in Jmol Part of the Jmol Training Guide from the MSOE Center for BioMolecular Modeling Interactive version available at http://cbm.msoe.edu/teachingResources/jmol/jmolTraining/started.html Introduction Physical models of proteins are powerful tools that can be used synergistically with computer visualizations to explore protein structure and function. Although it is interesting to explore models and visualizations created by others, it is much more engaging to create your own! At the MSOE Center for BioMolecular Modeling we use the molecular visualization program Jmol to explore protein and molecular structures in fully interactive 3-dimensional displays. Jmol a free, open source molecular visualization program used by students, educators and researchers internationally. The Jmol Training Guide from the MSOE Center for BioMolecular Modeling will provide the tools needed to create molecular renderings, physical models using 3-D printing technologies, as well as Jmol animations for online tutorials or electronic posters. Examples of Proteins in Jmol Jmol allows users to rotate proteins and molecular structures in a fully interactive 3-dimensional display. Some sample proteins designed with Jmol are shown to the right. Hemoglobin Proteins Insulin Proteins Green Fluorescent safely carry oxygen in the help regulate sugar in Proteins create blood. the bloodstream. bioluminescence in animals like jellyfish. Downloading Jmol Jmol Can be Used in Two Ways: 1. As an independent program on a desktop - Jmol can be downloaded to run on your desktop like any other program. It uses a Java platform and therefore functions equally well in a PC or Mac environment. 2. As a web application - Jmol has a web-based version (oftern refered to as "JSmol") that runs on a JavaScript platform and therefore functions equally well on all HTML5 compatible browsers such as Firefox, Internet Explorer, Safari and Chrome. -

Visualizing 3D Molecular Structures Using an Augmented Reality App
Visualizing 3D molecular structures using an augmented reality app Kristina Eriksen, Bjarne E. Nielsen, Michael Pittelkow 5 Department of Chemistry, University of Copenhagen, Universitetsparken 5, DK-2100 Copenhagen, Denmark. E-mail: [email protected] ABSTRACT 10 We present a simple procedure to make an augmented reality app to visualize any 3D chemical model. The molecular structure may be based on data from crystallographic data or from computer modelling. This guide is made in such a way, that no programming skills are needed and the procedure uses free software and is a way to visualize 3D structures that are normally difficult to comprehend in the 2D 15 space of paper. The process can be applied to make 3D representation of any 2D object, and we envisage the app to be useful when visualizing simple stereochemical problems, when presenting a complex 3D structure on a poster presentation or even in audio-visual presentations. The method works for all molecules including small molecules, supramolecular structures, MOFs and biomacromolecules. GRAPHICAL ABSTRACT 20 KEYWORDS Augmented reality, Unity, Vuforia, Application, 3D models. 25 Journal 5/18/21 Page 1 of 14 INTRODUCTION Conveying information about three-dimensional (3D) structures in two-dimensional (2D) space, such as on paper or a screen can be difficult. Augmented reality (AR) provides an opportunity to visualize 2D 30 structures in 3D. Software to make simple AR apps is becoming common and ranges of free software now exist to make customized apps. AR has transformed visualization in computer games and films, but the technique is distinctly under-used in (chemical) science.1 In chemical science the challenge of visualizing in 3D exists at several levels ranging from teaching of stereo chemistry problems at freshman university level to visualizing complex molecular structures at 35 the forefront of chemical research. -
