Here's the solution to question 1(b)(ii): Step 1: Recall the formula for the number of neutrons. The number of neutrons in an atom is calculated by subtracting the atomic number (number of protons) from the mass number (total number of protons and neutrons). Number of neutrons = Mass number - Atomic number Step 2: Calculate the number of neutrons for each isotope. Given: Atomic number of Neon (Ne) = 10. For the isotope with mass number 17: Number of neutrons = 17 - 10 = 7 For the isotope with mass number 19: Number of neutrons = 19 - 10 = 9 For the isotope with mass number 21: Number of neutrons = 21 - 10 = 11 The number of neutrons in the isotopes are: Mass number 17: 7 neutrons Mass number 19: 9 neutrons Mass number 21: 11 neutrons 3 done, 2 left today.
