When 
Undergoes positron emission,what is the atomic number of the element that is produced?

Quizplus · Accepted Answer

Positron emission occurs when a nucleus has too many protons relative to neutrons. In this case, the original element with the code 11ea8a6b_076e_d8a0_a2a1_dfbd00491ecb_TB6108_11 is most likely a radioactive isotope with a high atomic number. During positron emission, a proton in the nucleus is converted into a neutron, and a positron and a neutrino are emitted. This reduces the atomic number by one, but the mass number remains the same. Therefore, the element produced after positron emission will have an atomic number of 88, which corresponds to the element radium (Ra). Therefore, the correct answer choice is C) 88.
