Who is Dmitri Ivanovich Mendeleev?
100
It is a very light element and makes up 7.4% of the earth’s crust. It is used extensively in the manufacture of consumer goods because of its anti-corrosive properties. Upon its official discovery, the IUPAC and the ACS disagreed on the appropriate spelling of the name. Thus, the common spelling found in the US is not the generally accepted spelling throughout the rest of the world.
