General questions

[Freda7]

I have googled my fingers sore and still cannot come up with any answers for the following:
1. On which TV programme did Martha Carney regularly appear before taking over the news and current affairs programme The World At One.
2. Of which popular plaything and sporting item was "The Volito" an early form.
3. What are the two most common metallic elements in the human body.
Any help, whether it be hints, clues, answers, will be most appreciated.

I agree with Calcium, sgeandhu, but I get Phosphorous as the second
Wikipedia gives the element list

http://en.wikipedia.org/wiki/Abundance_of_the_ chemical_elements#Human_body

and FloraHealth describes Phosphorous as a metallic element, second only to calcium in the human body

Thank you all very much. I really had tried hard to find these answers but I just couldn't come up with any thing definite. All your help and advice is very much appreciated.

Phosphorus, (IPA: [ˈfɒsfərəs], Greek: ph�s meaning "light", and phoros meaning "bearer"), is the chemical element that has the symbol P and atomic number 15. A multivalent nonmetal of the nitrogen group, phosphorus is commonly found in inorganic phosphate rocks.

also from Wikipaedia...seems the jury is out on phosphorus being a metal :-)
