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.
The atomic number is what distinguishes one element from another in nature. For example, hydrogen has an atomic number of 1. An atom of hydrogen has a single proton and a single electron. Helium has an atomic number of 2.A single helium atom has 2 protons and 2 electrons. Copper has an atomic number of 29, so it contains 29 protons and 29 electrons.The atomic weight (sometimes called atomic mass) of an atom is approximated by the sum of the number of protons and the number of neutrons in the nucleus of the atom.he atomic number is what distinguishes one element from another in nature. For example, hydrogen has an atomic number of 1. An atom of hydrogen has a single proton and a single electron. Helium has an atomic number of 2.
