90 naturally occurring elements, unknown number possible elements.
Roughly, first ionization potential and electron affinity.
Total 108 elements are found in earth till 2007 dec 56 to 72 elements are in the human body, 22 to 36 are in the animal body 18 22 elements in birds are found
No Igneous rock is consistently a compound - a mixture of elements. Although there are variations in composition, igneous rock is usually made up of roughly half oxygen, roughly one quarter silicon, and lesser, but significant, quantities of aluminum, calcium, sodium, potassium, and magnesium., with a sprinkling of other elements.

Three metals areZinc, Molybdenum, CadmiumThree non-metals areHydrogenCarbonNitrogenOxygenPhosphorusSulfurSelenium(YOU CAN CHOOSE FROM THESE ) (THESE ARE JUST ALL OF THE ELEMENTS)Ih ope this helped you alot... :) I am sure you will get an A+++++ I LOVE YA
