Representations from the Periodic Table Oxidation States Atomic Number 29 +1 +2 Cu Copper 63.546 2-8-18-1 Symbol Name Atomic Mass Electron Configuration Electrons/Level
Calculating Number of Protons and Electrons Atomic Number 29 +1 +2 Cu Copper 63.546 2-8-18-1 Atomic Number for a neutral atom = # of Protons and Electrons
Calculating Number of Neutrons 29 +1 Cu Copper 63.546 2-8-18-1 +2 Neutrons = Mass Number Atomic Number If Most Common Isotope - Round Atomic Mass to nearest whole number so 64 AMU
Calculating Mass Number 29 +1 Mass Number = Sum of the protons and neutrons +2 Cu Copper 63.546 2-8-18-1
Isotope Name 29 +1 Element Name followed by hyphen and then Mass Number ex. Copper - 64 +2 Cu Copper 63.546 2-8-18-1
Isotope Notation m = mass number: # of Protons + Neutrons X = symbol of element 29 +1 m X +2 Cu Copper 63.546 2-8-18-1 p p = Atomic Number: # of protons 64 Ex = Cu 29
Final Answers for Copper Element / Symbol Isotope Name Isotope Notation Atomic Number Protons (p+) Neutrons (n0) Electrons (e-) Mass Number 64 Cu 29 Copper Cu Copper-64 29 29 35 29 64
