What effect does the presence of an extra neutron have on the chemical properties of the new atoms formed?

Respuesta:
The atomic nucleus is the central part of an atom, has a positive charge, and concentrates more than 99.9% of the total mass of the atom.
It is made up of protons and neutrons (called nucleons) that are held together by strong nuclear interaction, and detailed which allows the nucleus to be stable, despite the fact that the protons repel each other (like the equal poles of two magnets). The number of protons in the nucleus (atomic number), determines the chemical element to which it belongs. Atomic nuclei do not necessarily have the same number of neutrons, since atoms of the same element can have different masses, that is, they are isotopes of the element.
The existence of the atomic nucleus was deduced from Rutherford's experiment, where a thin gold foil was bombarded with alpha particles, which are helium atomic nuclei emitted by radioactive rocks. Most of these particles broke through the sheet, but some bounced off, proving the existence of a tiny atomic nucleus.
