The copper nucleus contains #29# protons, so we have #""^63Cu#. Show Explanation:The superscript is the sum of protons and neutrons, massive nuclear particles with a positive or a neutral charge. How did I know that copper has 29 protons in its nucleus? If I have a neutral atom of #""^63Cu#, how many electrons are there? IF there were 35 neutrons, how would I write the isotope? 1.2.1 IsotopesAll atoms of the same element have identical atomic numbers, and are chemically similar, but they may not be identical in other ways. Figure 2f shows copper. All copper atoms have atomic number 29: all their nuclei contain 29 protons. But they also contain uncharged particles called neutrons. In natural copper, the atoms are of two kinds. One has 29 protons and 34 neutrons in the nucleus; the other has 29 protons and 36 neutrons (Figure 4).  Figure 4 The distribution of protons, neutrons and electrons in the atoms of the two isotopes of copper present in copper metal. In both cases, the atomic number is 29: there are 29 protons in the nucleus. This makes both types of atom, atoms of copper, but they differ in the number of neutrons contained in their nucleus The two different kinds of atom are called isotopes of copper. The neutron has a mass very similar to that of the proton, so the two isotopes differ in mass. The sum of the numbers of neutrons and protons for a particular isotope is called the mass number. Question 3
Answer63 and 65 — that is, (29 + 34) and (29 + 36), respectively. The two isotopes are written, The mass number of any isotope is equal to the
relative atomic mass of its atom, rounded to the nearest whole number. The atoms of natural copper are about 70% Figure 5 A symbolism showing the number of neutrons, protons and electrons in the neutral atom of an isotope Copper 63: 29 protons, 29 electrons, 34 neutrons Copper 65: 29 protons, 29 electrons, 36 neutrons Copper 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.

Because the Cu 64 isotope is NOT naturally occurring and copper plates have been common targets starting with the
earliest high energy accelerator physics experiments, I doubt that one could figure out who was the first to discover that particular isotope. -Craig Return to “Grades 9-12: Physical Science” Jump to
