How many protons electrons neutrons in atom of copper? look on the periodic table of elements for Cu. it usually gives you the answer in the corners. 29 protons, 29 electrons (as these are always the same) and 35 neutrons (this is â¦ the atomic mass rounded to the nearest figure) hope this helps.
If two ions have the same number of electrons, they are referred to as isoelectronic. For instance, neutral copper has 29 electrons, while neutral nickel has 28. If the copper lost two electrons and the nickel lost one, you'd have Cu2+ and Ni+, each with 27 electrons. These two ions are isoelectronic.
