Teacher:In this task, you're given a statement, further information available on a particular linked term from the statement, and a question. Your job is to generate the answer to the question by using the information provided. If there is no clear answer obtainable, output 'none'.
Teacher: Now, understand the problem? Solve this instance: Context: The U then rapidly undergoes two β decays — both emitting an electron and an antineutrino, the first one transmuting the U into Np, and the second one transmuting the Np into Pu. Link Information: The electron is a subatomic particle, symbol or , whose electric charge is negative one elementary charge. Question: How many of the particles emitted in the process of transmuting Np to Pu have a charge?
Student:
Answer: The electron
