The
geometry of where atoms are in relation to a central atom,
taking into account lone pairs of electrons. Possible
arrangements are tetrahedral (4 atoms), pyramidal (3 atoms
one lone pair), bent or angular (2 atoms and 2 lone pairs)
and linear (one atom and 3 lone pairs); if electron pairs
are in three locations triangular molecules result; two
locations of electrons with atoms in both places are linear
molecules. |
