Video TranscriptIn this question, we have to show the balanced nuclear question Nuclear question of AL. For Nikki of plutonium 2 39 and the ballistic nuclear question of decay of plutonium two chinese, the symbol of plutonium is bu It's mass number is 239 and its atomic number is 94. That indicates, by emitting alpha radiation it is converted into uranium, Its atomic number decreases by two, It becomes 92 and its marks number decreases by four, it becomes 235, and the alpha is presented by ICI last two in western berries foot. So this is the nuclear question of alpha decay of plutonium 2009, which is the answer to this question.

Alpha decay. An example of this decay occurs in the uranium-238 nucleus that decays into thorium-234 nucleus. Alpha particle has a relatively large mass, positive electric charge, and poor radiation penetration, and it can be stopped by a paper sheet (Ilem-Ozdemir and Asikoglu, 2012).
What is the equation for alpha?Alpha Formula Calculator. What is the balanced chemical reaction of alpha decay?(The numbers following the chemical names refer to the number of protons plus neutrons.) In this reaction, uranium-238 loses two protons and two neutrons to become the element thorium-234. The reaction can be represented by this nuclear equation: 92 238 U → 90 234 T h + 2 4 H e + Energy.
