How to play Molecular Shapes Puzzle
There are 9 pictures of different types of molecule bondings, situated at the top of the screen. Drag and drop them in the squares under the correct chemical formula of the bonded compound. Arrange all 9 shapes correctly to win the game. Test your knowledge for this topic with the tries counter. 9 tries for A, 18 for F.
Know the simple molecular geometry types and get +1 Knowledge Level.
Class subject: VSEPR theory.
Valence Shell Electron Pair Repulsion theory, is a model used in chemistry to predict the geometry of individual molecules from the number of electron pairs surrounding their central atoms.
The idea of a correlation between molecular geometry and number of valence electron pairs was originally proposed in 1939 by Ryutaro Tsuchida in Japan, and was independently presented in a Bakerian Lecture in 1940 by Nevil Sidgwick and Herbert Powell of the University of Oxford.
