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.
In your case, 1 mole of copper will contain #6.022 * 10^(23)# atoms of copper. So, copper's molar mass is equal to 63.546 g. In other words, #6.022 * 10^(23)# atoms of copper have a mass of 63.456 g. In order to get the mass of an individual copper atom, divide this mass by how many copepr atoms are in 1 mole.
