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

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

Answer 1

In beta-plus decay, a proton in the nucleus is transformed into a neutron, and a positron is emitted. As a result, the mass number remains the same, and the atomic number decreases by one.

Thus, the correct response is:

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