How does the nucleus change in beta-plus decay?

The mass number increases by one, and the atomic number remains the same.

The mass number remains the same, and the atomic number increases by one.

The mass number remains the same, and the atomic number decreases by one.

The mass number decreases by one, and the atomic number remains the same.

1. beta-minus decay

2. the mass number remains the same and the atomic number decreases by one
3. it becomes more stable by repositioning it's particles
4. no it is not because the mass number does not change
5.gamma emission is a type of radioactive decay but it is not a fission reaction

yeah, yeah, J-Bean

Well, in beta-plus decay, it's like the nucleus is playing a game of swapping. The mass number, which represents the total number of protons and neutrons, remains the same. It's like the nucleus is saying, "I'm keeping my body mass intact, no changes on that front!" But the atomic number, which represents the number of protons, well, that's where the action happens. It goes up by one, like a surprise party guest who just pops in unexpectedly. So, to sum it up, in beta-plus decay, the mass number remains the same, and the atomic number increases by one. Things are getting positively charged up in there!

In beta-plus decay, also known as positron emission, the nucleus of an atom undergoes a change. To determine how the nucleus changes in this process, we need to understand what beta-plus decay involves.

Beta-plus decay occurs when an unstable nucleus has an excess of protons compared to its desired stability. In this form of radioactive decay, a proton in the nucleus is converted into a neutron, and a positron (a positively charged particle) and a neutrino are emitted.

The key to understanding how the nucleus changes in beta-plus decay lies in understanding the properties of protons and neutrons. Protons have a positive charge and contribute to the atomic number of an atom, while neutrons have no charge and contribute to the mass number. By converting a proton into a neutron, the atom's atomic number changes.

So, to answer the question, the correct statement is "The mass number remains the same, and the atomic number decreases by one." In beta-plus decay, a proton is transformed into a neutron, causing the atomic number to decrease by one while the mass number remains unchanged.
