How many known elements are on Earth?
As of 2010, there are 118 known elements (in this context, “known” means observed well enough, even from just a few decay products, to have been differentiated from other elements). Of these 118 elements, 94 occur naturally on Earth.
What is the number of known elements?
Elements are simple fundamental substances, commonly referred to as nature’s building blocks. Although there are at least 106 known elements, 98% of the planet is made up of only six elements: iron, oxygen, magnesium, silicon, sulfur and nickel.
