VSEPR Theory & Molecular Geometry Atoms of C, N, O
How many atoms does it take to produce a geometric angle??? ANSWER: Always three (3) atoms.
- The orientation of objects in space—visualizing spatial orientations in our mind's eye—can be a mental struggle.
(roll your mouse over or click on the image on the left).
IMPORTANT: Study the animation, noting the important symbolism shown below:
- Note the "
" represents electrons being shared between two atoms, and - This image
is used as our representation showing an electron cloud for non boned electrons about an atom. - Nonbonded pairs of electrons are NOT being shared between two atoms.
When visualizing atoms and their spatial orientation in a substance, remember these things known to be true:
1) the surface area of atoms and electrons are negatively charged,
2) The Law of Electrostatics - "like charges repel like charges" and seek the greatest degree of separation, and
3) three atoms are required to produce an angle & geometric "named" identifier about a central atom.
Applying the Law of Electrostatics, opposites attract and like charges repel, is important in our understanding of VSEPR theory–an empirical theory.
