Step 1: Identify the number of protons and neutrons for each isotope.
Part 1: The isotope with 18 protons and 17 neutrons is Oxygen- 18. The number of protons (also known as atomic number) determines the element, while the sum of protons and neutrons (also known as mass number) determines the isotope. Part 2: The isotope with 9 protons and 8 neutrons is Fluorine- 17.
Step 2: Write the isotope symbol using the correct format.
Part 3: The isotope with 17 protons and 20 neutrons is Argon- 37. The atomic number Z (number of protons) is 17, and the mass number A (sum of protons and neutrons) is 37. _{17}^{37}\text{Ar} Part 4: The isotope with 19 protons and 20 neutrons is Potassium- 39. The atomic number Z (number of protons) is 19, and the mass number A (sum of protons and neutrons) is 39. _{19}^{39}\text{K}
Final Answer
Part 1: Oxygen- 18 Part 2: Fluorine- 17 Part 3: Argon- 37 Part 4: Potassium- 39
