There are currently 118 known elements on the Periodic Table. These elements range from hydrogen, the lightest, to oganesson, the heaviest.
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.

They were all formed roughly around the same time from the same molecular cloud. This slowly collapsed over time, with the sun being formed at the centre.
