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.
Isotopes: Copper has 24 isotopes whose half-lives are known, with mass numbers 57 to 80. Naturally occurring copper is a mixture of its two stable isotopes, 63 Cu and 65 Cu, with natural abundances of 69.2% and 30.8% respectively.
