Tetrahedral Sulfur, SP1 67-96958, is represented by Tetrahedral
Phosphorous, SP1 67-6924 (see SP1 67-6924 to the left) when
used with four Long Connector Link, SP1 67-7021 (see SP1 677021 on page 70) resulting in a covalent radius of 1.04Å; doublebond face not differentiated.

69
A sphere with a diameter corresponding to
2.7Å. Lines of longitude and latitude are
embossed at 30° intervals over the surface
of the sphere. An indent is at one pole of the sphere. With the aid
of the lines of latitude and longitude, the user may orient the
sphere in any direction required by a particular construction.
This metal atom has a special connector. It is the SP1 67-7161
Metal Atom Connector Link, see page 71, and consists of a
connector link one-half the length of a normal link plus a selftapping screw. A 1/16 inch hole must be drilled in the sphere in
order to accommodate the self-tapping screw.
Two SP1 67-7161 Metal Atom Connector Links are included with
each SP1 67-6999 Metal, All Purpose. Silver.
