Well, perhaps not the most common element, but it is number 6. When I
wrote the email, I was thinking back to my qualitative/quantitative
chemistry classes in college some 25 years ago. I distinctly remember
sodium posing a contaimination issue/problem for classmates who did not
have good lab hygene - Bad hygene would cause unknowns to test positive
for it even though orgrinally no sodium was present.
