Mass number of copper = 63 Atomic number of copper = 29 As atomic number of element gives number of proton and electrons while mass number of element gives number of protons +number of neutrons. So, number of protons in copper = atomic number of copper = 29. Number of electron in copper = number of protons in copper =29. Number of neutrons = mass number atomic number = 63 29 =34. So answer is (iv) as copper contains 29 protons and 29 electrons.
