Answer

Explanation:

Step1: Recall atomic number and basic particle relationships

The atomic number (Z) is equal to the number of protons (p). For a neutral atom, the number of electrons (e) is equal to the number of protons. The number of neutrons (n) is calculated as mass number (A) - atomic number (Z).

Step2: Find particles for Pr (Praseodymium)

Pr has an atomic number of 59. Given mass number is considered as a whole - number for this problem. Let's assume mass number A = 141 (common isotope). p = 59 (from atomic number) n=A - Z = 141 - 59 = 82 e = 59 (for neutral atom)

Step3: Find particles for B (Boron)

B has an atomic number of 5. Assume mass number A = 11 (common isotope). p = 5 n=A - Z = 11 - 5 = 6 e = 5

Step4: Find particles for Te (Tellurium)

Te has an atomic number of 52. Assume mass number A = 128 (common isotope). p = 52 n=A - Z = 128 - 52 = 76 e = 52

Step5: Find particles for V (Vanadium)

V has an atomic number of 23. Assume mass number A = 51 (common isotope). p = 23 n=A - Z = 51 - 23 = 28 e = 23

Step6: Find particles for Mn (Manganese)

Mn has an atomic number of 25. Assume mass number A = 55 (common isotope). p = 25 n=A - Z = 55 - 25 = 30 e = 25

Step7: Find particles for I (Iodine)

I has an atomic number of 53. Assume mass number A = 127 (common isotope). p = 53 n=A - Z = 127 - 53 = 74 e = 53

Answer:

  1. Pr: p = 59, n = 82, e = 59
  2. B: p = 5, n = 6, e = 5
  3. Te: p = 52, n = 76, e = 52
  4. V: p = 23, n = 28, e = 23
  5. Mn: p = 25, n = 30, e = 25
  6. I: p = 53, n = 74, e = 53
