Population : A chemical element or element is a species of atoms having the same number of protons in their atomic nuclei ( i . e . the same atomic number , " Z "). There are 118 elements that have been identified , of which the first 94 occur naturally on Earth with the remaining 24 being synthetic elements . There are 80 elements that have at least one stable isotope and 38 that have exclusively radioactive isotopes , which decay over time into other elements . Iron is the ___MASK81___ abundant element ( by mass ) making up Earth , while oxygen is the ___MASK81___ common element in the Earth ' s crust . Flerovium is a superheavy artificial chemical element with symbol Fl and atomic number 114 . It is an extremely radioactive synthetic element . The element is named after the Flerov Laboratory of Nuclear Reactions of the Joint Institute for Nuclear Research in ___MASK99___ , Russia , where the element was discovered in 1998 . The name of the laboratory , in turn , honours the Russian physicist Georgy Flyorov ( in Cyrillic , hence the transliteration of " yo " to " e "). The name was adopted by IUPAC on 30 May 2012 .
