giggle ... well I sort of guessed you would but with over 90 views of this thread so far, I figured there's probably a few more reading than just you and I. Anyway on with the show...
So the key to understanding how elements behave is to understand this shell or orbit business
Now this is a real simplistic explanation of one of the ways
heavy metals get into a cell
When it comes to a plant wanting to take a certain nutrient out of the dirt like chromium
it can't just call out "hey I need some chromium here"
it looks for the metal with 6 electrons past the noble ( or inert ) gas column
and chromium, like molybdenum has an outer shell of 13, 1
but along comes tungsten which also has 6 electrons past the noble gas but it's shell structure is different at 22.214.171.124.12.2
result confusion, and a nutrient is taken up which sort of looks like the one we want but doesn't behave the way we want. Have a look herehttp://spectrumsleuth.10.forumer.com/vi ... .php?t=220
Have a look at another element Zinc, number 30 on the periodic table and have a look at the two immediately below it, Cadmium and Mercury
when a cell calls for some zinc it is really saying I want the metal 12 past the noble gas with a outer shell structure of 18,2
look at the structures of Cadmium and Mercury - both 18,2
That is why Mercury and Cadmium really stuff up Zinc, which is responsible for hundreds of enzyme reactions in the body
Have a look at Carbon and Silicon in group 14 and look below them to see the two heavy metals which mimic them - Tin and Lead
Essentially when you see on a chart ( eg hair test or urine test ) saying there is mercury, lead etc then you can look at the periodic table, find the element in question look directly above it and see what essential elements are going to directly affected. Got Bismuth 83 or Antimony 51 look above them ( group 15 ) and see that Nitrogen and Phosphorous will be affected.
