copper has more protons than nickel
The mass of a single copper atom is the same as the mass of a nickel atom.
The atomic number of copper is 29, which means that a copper atom has 29 protons in its nucleus.
A nickel weighs 5 grams. It is 75% nickel and 25% copper. The atomic weight of nickel is 58.71 and the atomic weight of copper is 63.54. So there is 0.0639 moles of nickel and 0.0197 moles of copper in a US nickel. There are 6.02 * 10^23 atoms in a mole (Avogadro's number). There are 6.02 * 10^23 * 0.0639 = 3.48 * 10^22 atoms of nickel, and 6.02 * 10^23 * 0.0197 = 1.184 * 10^22 atoms of copper. Since a nickel atom contains 28 electrons, and a copper atom contains 29 electrons, we have 9.744 * 10^23 electrons for the nickel component, and 3.433 * 10^23 electrons for the copper component. Total is 1.317 * 10^24 electrons.
An atom of copper-65 has 35 neutrons in its nucleus. This is calculated by subtracting the atomic number (which is 29 for copper) from the mass number (which is 65 for copper-65), as neutrons and protons together make up the mass number.

Comparison of nucleus of Cu atom and Ni atom: Cu atom has 29 protons and 34 neutrons. A Ni atom has 28 protons and 31 neutrons.
The charge of the nucleus of a copper atom is positive, equal to the number of protons in the nucleus. Copper has 29 protons, so the nucleus has a charge of +29 elementary charges, which is equivalent to +29 atomic units of charge (e).
The mass of a single copper atom is the same as the mass of a nickel atom.
The nucleus of an atom is much smaller than the volume of the entire atom. The nucleus makes up only a tiny fraction of the total volume, with the electrons surrounding the nucleus occupying the majority of the space.
