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.
Aluminum has 13 protons (because of its atomic number). It has 14 neutrons, 13 electrons, and has 3 valence electrons (valence electrons are determined by looking at its group #). IF you make a model of an atom and it has 17 electrons, you wouldn't put 17 elecetrons around the atom, you would put its valence electron around it.
