Multiple Choice QuestionWhen an isotope undergoes beta decay, a new isotope is produced with an atomic number that is ______.Multiple choice question.the sameless by oneless by fourgreater by one
Solution
The correct answer is "greater by one".
Here's why:
Beta decay is a type of radioactive decay where a beta particle (an electron or a positron) is emitted. In the case of beta minus decay (where an electron is emitted), a neutron in the nucleus of the atom is transformed into a proton. This increases the atomic number by one, but the mass number (total number of protons and neutrons) remains the same. Therefore, the atom becomes a new isotope of the next element in the periodic table.
