Let's analyze the given information for Potassium (K) and Fluorine (F):

  • Potassium (K)

    • Atomic number: 19 (which means it has 19 protons)
    • Mass number: 40
    • Neutrons: Mass number - Atomic number = 40 - 19 = 21
    • Electrons: In a neutral atom, the number of electrons equals the number of protons = 19

  • Fluorine (F)

    • Atomic number: 9 (which means it has 9 protons)
    • Mass number: 18
    • Neutrons: Mass number - Atomic number = 18 - 9 = 9
    • Electrons: In a neutral atom, the number of electrons equals the number of protons = 9

Now, let's match the questions with the correct answers:

  1. What is the atomic number of the Potassium atom?
    Answer: 19

  2. What is the mass number of the Fluorine atom?
    Answer: 18

  3. How many neutrons in the Potassium atom?
    Answer: 21

  4. How many electrons in the Potassium atom?
    Answer: 19

  5. How many neutrons in the Fluorine atom?
    Answer: 9

  6. How many protons in the Fluorine atom?
    Answer: 9

However, based on the choices given (18, 59, 9, 40, 21, 19, 27), here is the correct attribution based on the numbers available:

  1. What is the atomic number of the Potassium atom?
    Answer: 19

  2. What is the mass number of the Fluorine atom?
    Answer: 18

  3. How many neutrons in the Potassium atom?
    Answer: 21

  4. How many electrons in the Potassium atom?
    Answer: 19

  5. How many neutrons in the Fluorine atom?
    Answer: 9

  6. How many protons in the Fluorine atom?
    Answer: 9

Final Answers Summary:

  1. Potassium Atomic Number: 19
  2. Fluorine Mass Number: 18
  3. Potassium Neutrons: 21
  4. Potassium Electrons: 19
  5. Fluorine Neutrons: 9
  6. Fluorine Protons: 9
