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.
One gram of copper contains 9.47 * 10^(21)atoms of copper The be able to determine the mass of an individual copper atom, you need to use copper's molar mass. Copper's molar mass expresses the mass of 1 mole of copper atoms. One mole of any substance contains exactly 6.022 * 10^(23) atoms or molecules of that substance - this is known as Avogadro's number. In your case, 1 mole of copper will contain 6.022 * 10^(23) atoms of copper.
