 What is an element?  Chemically, an element is a pure substance composed of
atoms that all have the same number of protons in the nucleus.  That number
is the "atomic number" and specifies the element's position in the periodic
table.  The atomic nucleus also contains neutrons.  For each element, the
sum of the numbers of protons and neutrons is the approximate atomic weight.
Depending on the definition, 17 out of the 94 naturally occurring elements
are generally considered essential for the growth of plants.

Cool. And how much CO2 and H2O does it take to make an ounce of glucose?

I do not have the answer.  You seem to know much more than me about
chemistry.

could you define two things for me please?

nutrient -

element -

Thanks

This is an old tip that I've never had the occasion to test directly (but I
will comment more after):

Drive a small spade down in one or two spots  around one of your
plants and cut a few roots.  This might shock the plant into ripening
the tomatoes.

OK, this year one of the new varieties I was trying was not ripening any
tomatoes, not even a hint of color, even after all the others were doing
so.  It was so full of green tomatoes that the stake was leaning over
threatening to crash into the fence. (I have electric wires at the top so
this would have been a Bad Thing.)   I drove in a couple of small stakes
to tie off the larger one and stop the leaning.  And shortly after that, a
whole bunch of tomatoes on that plant started turning red.

 Now, I would think this was entirely coincidental, except for having
remembered that old advice.  So I may have unintentionally confirmed it
works.  Or, maybe not.  I doubt it would hurt to try.
