In problems 5.51 to 5.54, a nucleus is shown with protons and neutrons.
Draw the new nucleus when this isotope emits a positron to complete the following:

Positron emission is a type of radioactive decay in which a proton in the nucleus is transformed into a neutron, resulting in the emission of a positron (the antimatter counterpart of an electron). This process decreases the atomic number of the element by one while keeping the mass number the same, leading to the formation of a new isotope.

The nucleus of an atom is composed of protons and neutrons, collectively known as nucleons. Protons carry a positive charge, while neutrons are neutral. The balance between these particles determines the stability of the nucleus and influences the type of decay it may undergo, such as positron emission.

Isotopes are variants of a chemical element that have the same number of protons but different numbers of neutrons. This difference in neutron count results in varying atomic masses. Isotopes can be stable or unstable, with unstable isotopes undergoing radioactive decay, such as positron emission, to achieve a more stable configuration.
