QI - What's The Commonest Metal In The Human Body?

mauz15 says...

>> ^Sagemind:
What do they mean by commonest????
We all have iron in common
We all have calcium in common.
Are there some people out there without iron which makes calcium more common?
The question is flawed from the start!


Commonest as in the most common, most widespread, or most frequently encountered. Many of the other metals found in the body are in extremely minute quantities. We are talking of quantities such as less than 0.07% of the human body, compared to 1.5% of Calcium. This 1.5% may not seem like much, but Calcium is part of the 6 major elements in your body. These 6 are practically 99% while the other 1 percent is distributed among several other elements (like 60) so you can imagine the insignificant quantities.

Yeah Calcium is a metal, but the inorganic part of bones (bone is 2/3 inorganic matter and one third of organic) is made primarily of hydroxyapatite (85%), which is a crystallized form of the Calcium Phosphate salt. The rest of the inorganic part is Calcium Carbonate, and small amounts of magnesium, fluoride, sulfate, potassium, etc.

Chloride by itself is a deadly gas, sodium by itself is a very volatile metal. But if you get sodium chloride the result is table salt. In the same way, Calcium by itself is a metal and therefore would behave like one, but when it gets together with phosphate in the right combination you get the main component of bones.



>> ^ForgedReality:
Calcium is a metal? O.O Why doesn't everyone set off metal detectors then? How do people work around huge magnets, like in a wrecking yard, without being stuck to them? Why don't bones rust? Why don't bones make sparks when a bone saw is applied? Why in the hell do some people think it's a good idea to put onions in when making a tuna fish sandwich?

^ yeah, because the conditions necessary for fossilization to occur are extremely common.

What are the conditions necessary for a fossil to form? I suddenly forgot about such typical event.

I remember some of them, like: low levels of bacteria, absence of scavengers, perfect temperature, soil, PH levels, weather, anaerobic conditions, the chances for mineralization to occur,etc, etc, etc.

Very typical.
