There are 29 Protons and 34 Neutrons in Copper-63. There are also 29 Protons and 36 Neutrons in Copper-65. Those are the only two stable isotopes of copper.

## Related Questions Copper has 29 protons and electrons and 63 or 65 neutrons, depending on the isotope. Copper is element 29 and so 29 protons and thus 29 electrons to balance. 63-29 = 34 so there are 34 neutrons with Copper 63. The isotope copper-64 has 29 protons and 34 neutrons. 29 protons, 29 electrons The number of neutrons depends on the isotope of copper. Cu-63 has 34 neutrons and Cu-65 has 36 neutrons.   The atomic number of copper is 29. So there are 29 protons and 29 electrons. The number of neutrons depends on the isotope. In Cu-63 isotope, there are 34 neutrons (63 - 29 = 34). Copper 63: 29 protons, 29 electrons, 34 neutronsCopper 65: 29 protons, 29 electrons, 36 neutronsCopper The number of protons in an atom of an element is the same as the atomic number. So finding the number of protons in an atom just consists of looking at a periodic table. Copper's atomic number is 29, so it has 29 protons.In a neutral atom, the number of electrons will equal and balance the number of protons, so it would also be 29 electrons.The number of neutrons will depend on the isotope you have. Atoms of the same element can exist with different numbers of neutrons - these are what we call isotopes. However, there are only two isotopes of copper, 63Cu and 65Cu, which have 34 and 36 neutrons respectively. There are 63 electrons and protons in Europium and 89 neutrons. The defining characteristic of an element is the number of protons in the nucleus. Copper always has 29 protons. It may have different numbers of neutrons, as in the common isotopes copper-63 and copper-65 which have 34 and 36 neutrons respectively. europium's atomic number is 63, it's mass (in amu's [atomic mass units]) is 152, rounded. the atomic number = the number of protons, so europium has 63 protons. the number of protons = the number of electrons, so there are 63 electrons in a europium atom. the mass= protons + neutrons, therefore neutrons = mass - protons. this would be 152 - 63 = 89 there are 89 neutrons in a europium atom. p+: 63 n: 89 e-: 63 hope i helped! ^.^ Isotopes Atoms have protons and neutrons in the nucleus and electrons in the shells. The number of protons = the number electrons The mass of the atom is due to the protons and neutrons in the nucleus. Copper is number 29 on the periodic table, which means all copper atoms have 29 protons in the nucleus. Copper has two naturally occurring isotopes. Cu- 63 has 29 protons and 34 neutrons and has an atomic mass of 62.93. Cu-65 has 29 protons and 34 neutrons and has an atomic mass of 64.93.Isotopes have different numbers of neutrons. An atom of copper contains 29 protons, 29 electrons, and either 34 or 36 neutrons depending on the isotope.  34 neutrons. this is because the atomic mass of copper is 63.5 and atomic number is 29. since number of neutrons is equal to atomic mass-atomic number (63-29). we get 29 neutrons. 34 and 36 neutrons in its two common isotopes, Cu-63 and Cu-65 respectively.  63-29 = 34 neutrons 29 = atomic number of copper 34 and 36 neutrons in Cu-63 and Cu-65 isotopes respectively Since chromium has an atomic number of 24, each atom of it contains 24 protons. The number of neutrons can be found by subtracting the atomic number from the mass number. Thus, chromium-63 has 39 electrons. Number of neutrons = Mass number - Atomic number = 63 - 29 = 34 neutrons Isotope Ni-63 has 28 electrons (it is found by looking at the atomic number for Nickel on the periodic table) and has 35 neutrons (which is found by subtracting the number in the isotope, 63, by the atomic number, 28) Cadmium has an atomic number of 48, therefore it has 48 protons in the nucleus and 48 electrons in the neutral atom. There are a number of isotopes (list from wikipedia article Cadmium) 106Cd 58 neutrons 108Cd 60 neutrons 111Cd 63 neutrons 112Cd 64 neutrons 113Cd 65 neutrons 114Cd 66 neutrons 116Cd 68 neutrons Because copper has isotopes. All Copper atoms have exactly the same number of protons, but not all of them have the same number of neutrons. The ones with different numbers of neutrons are known as isotopes. A given sample of Copper will contain various amounts of each of its isotopes. The atomic mass (weight) is an average weight, based on the percentages of the isotopes Number of neutrons = Mass number - atomic number = 63 - 24 = 39
