Explore Lab Writeup - Exploring Molecular Shapes
1)The question we were trying to answer was the # of things around central atom affect the shape of a molecule. 2)What we did for our investigation was use a VSEPR (valence shell electron pair replusion) simulation. We did this to predict the shape of a molecule from the # of atoms and lone electron pairs around central atom. 3)Our claim was when more things were added, the central atom appeared smaller. Our evidence was this, (it's the picture of our molecules with their angles and if they had a sing,doubl,tripl and lone pair bond. My reasoning was that model allows us to use the e- dot structures of atoms to predict the 3D Geometry of simple molecules. It was determined by the # of things surrounding a central atom. Also for lone pairs, lone pairs didn't really change the shape but change the electron name of the molecule.
