The following photos show how to assemble a molecule of methane from two different molecular model kits.
![]() | These are the pieces used to assemble the molecular models of methane. On the left are four hydrogen atoms and one tetrahedral carbon center. On the right are four hydrogen atoms, four green tubes which are bonds, and one tetrahedral carbon center. |
![]() This is the assembled model for methane from each model kit. The molecular shape of methane is tetrahedral and the electron
pair geometry is tetrahedral.
|
![]() The Octet rule is satisfied in each model. The four arrows shown in each image point to a pair of electrons.
Each carbon atom has eight electrons in its outer shell. Fulfillment of the Octet Rule may also be visualized
in the structural formula for methane.
