Answer:
Superscript 239 subscript 94 upper P u
(plutonium-239)
Explanation:
In alpha decay, the element subtracts 4 from its mass number and subtracts 2 from its atomic number.
So if we end with Uranium-235, which has an atomic number of 92:
235+4 = 239
92+2 = 94
Element 94 is Pu, plutonium, and its mass could very well be 239 if it's an isotope. So the answer is Superscript 239 subscript 94 upper P u.
