CHEMISTRY PLEDGE

(By the "Demo-A-Day" guys:  Borislaw Bilash II and John Koob)

I pledge allegiance to the chart of

the Periodic Table of Elements,

and to the Atomic Theory for which it stands.

One concept, under Mendeléev,

for observations and experimentation for all.

ANOTHER CHEMISTRY PLEDGE

I pledge allegiance to the periodic table

And to the theory for which it stands,

One theory, under Moseley,

With symbols and numbers for all.
