WebJun 28, 2024 · The general reaction is as follows: A ZXparent → A − 4 Z − 2X ′ daughter + 4 2αalphaparticle. The daughter nuclide contains two fewer protons and two fewer neutrons than the parent. Thus α-particle emission produces a daughter nucleus with a mass number A − 4 and a nuclear charge Z − 2 compared to the parent nucleus. WebThe atomic symbol for plutonium is Pu, and it has an atomic number of 94 and atomic weight of 244. On a periodic table you will find plutonium in period 7 belonging to the group called actinides . The element displays four common ionic oxidation statesin aqueous solutionand one rare one:[14] Pu(III), as Pu3+(blue lavender) Pu(IV), as Pu4+(yellow brown) Pu(V), as PuO+ 2(light pink)[note 1] Pu(VI), as PuO2+ 2(pink orange) Pu(VII), as PuO3− 5(green)—the heptavalent ion is rare.
