Let's work through the questions on your worksheet.

### Part 1: Fill in the Missing Blocks

To fill in the missing information for each element in the table:

1. **Boron (B)**:
   - Atomic Number: 5 (from the periodic table).
   - Protons: 5.
   - Neutrons: Mass Number - Protons = 11 - 5 = 6.
   - Electrons: 5 (since the atom is neutral).
   - Mass Number: 11 (given).

2. **Element with Atomic Number 43 (Technetium, Tc)**:
   - Protons: 43.
   - Neutrons: Mass Number - Protons = 100 - 43 = 57.
   - Electrons: 43 (since the atom is neutral).
   - Mass Number: 100.
   - Atomic Mass: 99 (since Atomic Mass and Mass Number are usually very close).

3. **Element with 81 Protons (Thallium, Tl)**:
   - Atomic Number: 81.
   - Protons: 81.
   - Neutrons: Mass Number - Protons = 206 - 81 = 125.
   - Electrons: 81 (since the atom is neutral).
   - Mass Number: 206.

### Part 2: Write the Numbers of Protons, Neutrons, and Electrons for Given Isotopes

For each isotope, use the periodic table to find the atomic number (protons) and calculate the rest:

1. **Chromium-58**:
   - Protons: 24 (atomic number of Chromium).
   - Neutrons: 58 - 24 = 34.
   - Electrons: 24 (since the atom is neutral).

2. **Chromium-63**:
   - Protons: 24.
   - Neutrons: 63 - 24 = 39.
   - Electrons: 24.

3. **Carbon-12**:
   - Protons: 6 (atomic number of Carbon).
   - Neutrons: 12 - 6 = 6.
   - Electrons: 6.

4. **Carbon-14**:
   - Protons: 6.
   - Neutrons: 14 - 6 = 8.
   - Electrons: 6.

5. **Nitrogen-15**:
   - Protons: 7 (atomic number of Nitrogen).
   - Neutrons: 15 - 7 = 8.
   - Electrons: 7.

6. **Nitrogen-20**:
   - Protons: 7.
   - Neutrons: 20 - 7 = 13.
   - Electrons: 7.

7. **Sulfur-23**:
   - Protons: 16 (atomic number of Sulfur).
   - Neutrons: 23 - 16 = 7.
   - Electrons: 16.

8. **Sulfur-25**:
   - Protons: 16.
   - Neutrons: 25 - 16 = 9.
   - Electrons: 16.

### Part 3: Fill in the Missing Information for Isotopes

1. **Iodine-113**:
   - Protons: 53 (atomic number of Iodine).
   - Neutrons: 113 - 53 = 60.
   - Electrons: 53.

2. **Iodine-111**:
   - Protons: 53.
   - Neutrons: 111 - 53 = 58.
   - Electrons: 53.

3. **Iron-27**:
   - Protons: 26 (atomic number of Iron).
   - Neutrons: 27 - 26 = 1.
   - Electrons: 26.

4. **Iron-30**:
   - Protons: 26.
   - Neutrons: 30 - 26 = 4.
   - Electrons: 26.

Would you like more details or have any questions about the calculations? Here are five questions that can help expand on the information:

1. How do you determine the atomic mass of an element?
2. What is the difference between atomic mass and mass number?
3. How do isotopes of the same element differ from one another?
4. Why is the number of protons equal to the number of electrons in a neutral atom?
5. How does the number of neutrons affect the stability of an isotope?

**Tip:** Remember, isotopes of an element have the same number of protons but different numbers of neutrons. This difference can impact the isotope's stability and radioactive properties.

Worksheet problem asking for the calculation of protons, neutrons, and electrons for elements and isotopes, and filling in missing information in the table.
