The nucleus of an atom is far too small to be "seen" in any conventional sense. The structure of the atom, that is, the one with most of the mass of the atom concentrated in the center, or nucleus, was developed by physicist Ernest Rutherford. In a sense, he is the one who first "saw" the nucleus of the atom. A link to the Wikipedia article on the atom, an article which includes the history of discoveries that lead to modern concepts of it, is provided. A link is also provided to the Rutherford model of the atom, also at Wikipedia. Hey, the nice folks at Wikipedia post knowledge for free. Why not surf on over and help yourself? It's a buffet, with all you can eat.
the denser part of an atom is the nucleus. about 99% of the mass of an atom is concentrated within the atom.
The center of an atom is called a nucleus (nucleifor plural).Center of an atom is called the "Nucleus".
Nuetrons are found in the center of an atom which is called the nucleus.
Protons of an atom are found only in its nucleus.
The proton is located in the atom's nucleus, with the neutrons (if there are any).
The number of protons in an atom's nucleus determines its chemical identity.
The gold-foil experiment
He identified the alpha particle as a helium atom and used it in postulating the existence of the atomic nucleus.
Atoms are normally identified according to the element of which that atom is an example. And that, in turn, is determined by the number of protons in the atom's nucleus. So, any atom that has just one proton is a hydrogen atom. If it has two protons it is a helium atom. And so forth.
Their atomic number, which represent the number of protons in the nucleus. This will also be the number of electrons in the unionised state of the atom.

The nucleus forms the centre of the atom. The protons and neutrons are found in the nucleus of the atom.
