Molecule Shapes

Which of the following does not determine the shape of a molecule?

• electron pairs around the central atom

• lone pair of electrons on other attached atoms

• lone pair of electrons around the central atom

• number of attached atoms

Why do the bonds in molecules want to be as far apart from each other as possible?

• the electrons that make up the bonds attract each other

• the electrons that make up the bonds repel each other

• the protons in the atoms repel each other

• there is no reason, the bonds just form far apart from each other
