Based on the placement of lone atoms and also based on the bonding of pairs the molecular geometry of an atom can differ. The shape of an atom can be bent, linear, tetrahedral, or triangular planar. They come with different sets of characteristics, since these shapes are different from each other. One of the characteristics, the angle that shows how far apart the bonds are from each other, the degree angle, determines the shape of the molecule. For example, a bond angle of 120 degrees would be a triangular planar shaped molecule. .
This experiment should show how different types of bonding affects the way the molecule is physically shaped. The different bonds and lone pairs are placed in certain locations so that each bond is of equal distance from each other. In all geometrical shapes of the molecule, this is seen. The bonds got closer to each other as more bonds were added, yet they still remained to stay away the same distance. The shape of a molecule is dependent on the bonds repelling each other due to their charges. This experiment was done to come up with a rule that applies to why certain molecules have certain molecular bonding. The bonds have angles to show how far apart the bonds are, which is due to the fact that the electrons repel each other. The forces repel to keep from colliding into one another. The molecule does this to even out its charges and in turn keeps the bond angles an equal distance apart. .
Bond pairs that are linearly shaped have bonds that are 180 degrees away from each other. The energy within the bonds create this distance because the bonds aren't attracted. The distance will become larger when a third bond is added; it'll have a bond angle of 120 degrees which is a bent shape. The repulsion keeps the bonds the same distance apart, even though the degrees became larger. If a lone pair was taken out to be a fourth bond, the shape would be more tetrahedral like instead of bent.
