[Pages:61]The Scope of Inorganic Chemistry

Medicine ?MRI ?X-ray contrast imaging ?drugs (arthritis, cancer,...

Biochemistry/Biology ? metalloproteins ? metalloenzymes ? O2 binding ? catalysis ? ion transport

Organic Chemistry ? organometallics ? metal compounds in

synthesis/catalysis

INORGANIC CHEMISTRY ? new compounds ? geometrical and electronic structures ? reactivity

Materials Science ? electrical and magnetic

properties of solids ? solid state structures ? semiconductors ? superconductors (high Tc)

Geology/Geochemistry ? synthesis and structure

of minerals ? stellar evolution ? astrochemistry

Organometallic Chemistry ? new compounds ? structures ? catalysis

If some universal catastrophe were to engulf the world, and humankind Could retain one scientific concept in order to rebuild civilization, what

would that one concept be?

Response for physicists (Richard Feynman in "Six Easy Pieces"):

The modern idea of atoms.

Response for chemists:

The periodic table The periodic table encapsulates the concept of elements, organizes physical and chemical trends of substances, and compares the structure of the different atoms-- All in a very small space.

Inorganic Chemists think they own the Periodic Table.

So, How did it all start?
