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.
Let's check out tin. Tin has more stable isotopes than any other element. There are 50 protons in every tin atom (which is what makes it tin), and there are isotopes of tin that have 62, 64, 65, 66, 67, 68, 69, 70, 72 and 74 neutrons which are all stable. There are some gaps in there, but there are isotopes of tin that fill in the gaps and also a lot of other isotopes, and they are made in the physics lab.
