The nucleus of an atom is positively charged and has a high density.
The nucleus of an atom is located in the center of the atom, it has a positive electrical charge and it is there that at least 99% of the absolute volume of the atom is found.
This central part is made up of protons and neutrons that remain united thanks to the strong nuclear interaction that enables the nucleus to remain balanced even when the protons repel each other.
Being so small, the matter is highly concentrated in the nucleus, with very high densities (on the order of 1018 kg / m3).
In this way, most of the atomic nuclei smaller than a certain atomic weight and that have a leveling in the number of neutrons and protons, are stable.
Therefore, we can conclude that the nucleus of an atom is located in the center of the atom, is positively charged and has a high density because it is so small.
