Answer 1

After line 1:
periodicTable is {'H': 'Hydrogen', 'O': 'Oxygen', 'N': 'Nickel'}

After line 2:
periodicTable is {'H': 'Hydrogen', 'O': 'Oxygen', 'N': 'Nickel', 'He': 'Helium'}

After line 3:
periodicTable is {'H': 'Hydrogen', 'O': 'Oxygen', 'N': 'Nickel', 'He': 'Helium', 'Au': 'Gold'}

After line 4:
periodicTable is {'H': 'Hydrogen', 'O': 'Oxygen', 'N': 'Nitrogen', 'He': 'Helium', 'Au': 'Gold'}

After line 5:
periodicTable is {'H': 'Hydrogen', 'O': 'Oxygen', 'N': 'Nitrogen', 'He': 'Helium', 'Au': 'Gold'}

After line 6:
periodicTable is {'H': 'Hydrogen', 'N': 'Nitrogen', 'He': 'Helium', 'Au': 'Gold'}
