We can use the following notations when examining a Lewis structure of a molecule.Į = non-bonding electron pairs of the central atom This theory basically says that bonding and non-bonding electron pairs of the central atom in a molecule will repel (push away from) each other in three dimensional space and this gives the molecules their shape. VESPR stands for valence shell electron pair repulsion. It applies a theory called VESPR for short. Molecular geometry is a way of describing the shapes of molecules. Similar logic applies to all the shapes, you just have to remember which "spoke" will be taken up by an electron pair. Once there are any electron pairs, one spoke of the original shape gets "eaten up": for example, a #AX_4E_2# is an octahedron shape, but the two "spokes" are taken up by electron pairs, so you're left with just the square-a square planar shape. #6#: octahedron (a flat square with two "spokes") #5#: trigonal bipyramid (a trigonal planar shape with two "spokes") #3#: trigonal plane (a flat equilateral-triangle-looking shape) ![]() ![]() As it has a VSEPR shape #AX_5E_0# it is a trigonal bipyramid.Įach steric number has a same "basic shape": Its steric number is #5# due to the #5# bonded atoms to the central #S# atom plus #0# lone electron pairs. Thus, it is in the form #AX_3E_1#, which forms a trigonal pyramidal shape. #N#, the central atom, has a steric number of #4#, calculated by the #3# atoms it's bonding with #+1# lone pair. This is the total number of electron pairs and bonds with other atoms. Find the central molecules' steric numbers. ![]()
