mimi makes a table about the two types of beta decay.\n|type of decay|particle released|change to nucleus|change to mass number|change to atomic number|\n|--|--|--|--|--|\n|beta plus|positron|proton changes to neutron|no change|decrease by 1|\n|beta minus|electron|neutron changes to proton|decrease by 1|increase by 1|\nwhat error did mimi make?\no no change in mass number occurs in beta minus decay.\no the changes to atomic number are reversed.\no a proton is released in beta plus decay.\no the changes to the nucleus are reversed.
Answer
Brief Explanations:
In beta - minus decay, a neutron changes to a proton, an electron, and an antineutrino. The mass number remains the same because the total number of nucleons (protons + neutrons) is unchanged. Mimi wrongly stated that the mass number decreases by 1 in beta - minus decay.
Answer:
No change in mass number occurs in beta minus decay.
