If you were an element, what element are you and in what another element would you like to bind with and why?

If I were an element, I would want to be Carbon. I would want to combine with  oxygen. It would create carbon dioxide. It has daily life uses. For heat, and for refridgment and more.

Explanation:

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
