How Many Protons and Neutrons Are Contained in the Nucleus of 63 29Cu? How Many Electrons Are Present in the Atom?

The nucleus of ⁶³₂₉Cu contains 29 protons and 34 neutrons. The number of protons is determined by the atomic number, which is 29 for copper (Cu). The number of neutrons is calculated by subtracting the atomic number from the mass number (63 – 29 = 34).

In a neutral atom, the number of electrons is equal to the number of protons. Therefore, the atom of ⁶³₂₉Cu has 29 electrons.
