Bohr Model Practice Problems Name: ___________________________ H Chemistry Week 12 Date/Period: _____________________ – For each atom, determine the number of protons, electrons, and neutrons, place each in the proper location in the atom, and then write a sentence describing the location of the protons and neutrons, and how many electrons are in each energy level. Remember the maximum number of electrons for each energy level follows the equation: 2n2, where is the principal energy level. n Guided Practice Example (“We Do”)”: Sodium-23, 2311Na N0 = Atomic Mass Atomic Number – N0 = _________ -- ____________ = ___________ # Valence Electrons = ________________ Chlorine 37 , 3717Cl – N0 = Atomic Mass Atomic Number – N0 = _________ -- ____________ = ___________ # Valence Electrons = ___________________
