Therefore, the least metallic elements are the opposite: the right and uppermost elements on the periodic table. What is the least metallic element on the periodic table? What is the most explosive element on the perodic table? A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. It is a silvery-white metal in the actinide series of the periodic table. It is a chemical element with symbol U and atomic number 92. The heaviest naturally occuring element is uranium. What is the heaviest element on the periodic table of elements? These strange elements are all the ones on the periodic table that have an atomic number greater than that of uranium – 92 – and they’re super-unstable, decaying into a bunch of other elements. What is the rarest element on the periodic table?Īccording to the guys at From Quarks to Quasars, who made the awesome infographic above, astatine is the rarest naturally occurring element that isn’t a transuranic element. They are very reactive but less so than the alkali metals. Group 2 consists of the alkaline Earth metals. The alkali metals are the most reactive metals. What are the 3 most reactive groups on the periodic table? It rapidly reacts with water to form caesium hydroxide and hydrogen gas.įluorine is the most reactive element among the given elements. Which is the highly reactive metal? Which is the most reactive element in the reactivity series? Which is the most reactive?įluorine is the most reactive element in the periodic table. Francium, however, is a laboratory-produced element and only minute quantities have been made, so for all practical purposes, the most reactive metal is cesium. The most reactive metal on the periodic table is francium. What is the most reactive element on the periodic chart Why?Ĭaesium is the most reactive metal in the periodic table, so much that working with this metal often ends in explosions! ![]() What is the most reactive element in a periodic table?Ĭesium is second from the bottom of this group, has 6 shells of electrons, and it matches the features of a reactive atom, making it the most reactive element. ![]()
