Explanation:

To solve the missing parts of the table, we use the relationships between atomic number, protons, neutrons, electrons, mass number, and charge:

1. For the row with atomic number 29 (Copper, Cu):

• Protons: Atomic number = protons, so protons = 29.
• Neutrons: Mass number = protons + neutrons. From the table, mass number is missing, but neutrons = 35 (given). Wait, mass number = 29 (protons) + 35 (neutrons) = 64.
• Electrons: Charge = 0 (neutral), so electrons = protons = 29.
• Mass Number: 29 + 35 = 64.
• Element Name: Copper (Cu).
• Atomic Symbol w/ Isotope Notation: \( \ce{^{64}_{29}Cu} \).

2. For the row with electrons = 39 (Yttrium, Y):

• Protons: In neutral atoms, electrons = protons. But charge = 0, so protons = 39.
• Atomic Number: Atomic number = protons = 39.
• Neutrons: Mass number = 89 (given), so neutrons = 89 - 39 = 50.
• Element Name: Yttrium (Y).
• Atomic Symbol w/ Isotope Notation: \( \ce{^{89}_{39}Y} \).

3. For Gallium (Ga):

• Mass Number: Protons (31) + Neutrons (37) = 68 (matches given mass number).
• Electrons: Charge = 0, but given electrons = 28. Wait, charge = protons - electrons = 31 - 28 = +3. So charge should be +3 (correction: table may have a typo, but using \( \text{charge} = p - e \), \( 31 - 28 = +3 \)).
• Atomic Symbol w/ Isotope Notation: \( \ce{^{68}_{31}Ga^{3+}} \) (if considering charge) or \( \ce{^{68}_{31}Ga} \) (neutral, but electrons don’t match).

4. For Sodium (Na):

• Mass Number: Protons (11) + Neutrons (13) = 24 (matches given mass number).
• Electrons: Charge = +1, so \( e = p - \text{charge} = 11 - 1 = 10 \) (matches given electrons).
• Atomic Symbol w/ Isotope Notation: \( \ce{^{24}_{11}Na^+} \).

5. For Technetium (Tc):

• Mass Number: Protons (43) + Neutrons (57) = 100 (matches given mass number).
• Electrons: Charge = 0, so electrons = protons = 43 (matches given electrons).
• Atomic Symbol w/ Isotope Notation: \( \ce{^{100}_{43}Tc} \).

6. For Lead (Pb²⁺):

• Mass Number: Protons (82) + Neutrons (125) = 207 (matches given mass number).
• Electrons: Charge = +2, so \( e = p - \text{charge} = 82 - 2 = 80 \) (matches given electrons).
• Atomic Symbol w/ Isotope Notation: \( \ce{^{207}_{82}Pb^{2+}} \).

Answer:

To solve the missing parts of the table, we use the relationships between atomic number, protons, neutrons, electrons, mass number, and charge:

1. For the row with atomic number 29 (Copper, Cu):

• Protons: Atomic number = protons, so protons = 29.
• Neutrons: Mass number = protons + neutrons. From the table, mass number is missing, but neutrons = 35 (given). Wait, mass number = 29 (protons) + 35 (neutrons) = 64.
• Electrons: Charge = 0 (neutral), so electrons = protons = 29.
• Mass Number: 29 + 35 = 64.
• Element Name: Copper (Cu).
• Atomic Symbol w/ Isotope Notation: \( \ce{^{64}_{29}Cu} \).

2. For the row with electrons = 39 (Yttrium, Y):

• Protons: In neutral atoms, electrons = protons. But charge = 0, so protons = 39.
• Atomic Number: Atomic number = protons = 39.
• Neutrons: Mass number = 89 (given), so neutrons = 89 - 39 = 50.
• Element Name: Yttrium (Y).
• Atomic Symbol w/ Isotope Notation: \( \ce{^{89}_{39}Y} \).

3. For Gallium (Ga):

• Mass Number: Protons (31) + Neutrons (37) = 68 (matches given mass number).
• Electrons: Charge = 0, but given electrons = 28. Wait, charge = protons - electrons = 31 - 28 = +3. So charge should be +3 (correction: table may have a typo, but using \( \text{charge} = p - e \), \( 31 - 28 = +3 \)).
• Atomic Symbol w/ Isotope Notation: \( \ce{^{68}_{31}Ga^{3+}} \) (if considering charge) or \( \ce{^{68}_{31}Ga} \) (neutral, but electrons don’t match).

4. For Sodium (Na):

• Mass Number: Protons (11) + Neutrons (13) = 24 (matches given mass number).
• Electrons: Charge = +1, so \( e = p - \text{charge} = 11 - 1 = 10 \) (matches given electrons).
• Atomic Symbol w/ Isotope Notation: \( \ce{^{24}_{11}Na^+} \).

5. For Technetium (Tc):

• Mass Number: Protons (43) + Neutrons (57) = 100 (matches given mass number).
• Electrons: Charge = 0, so electrons = protons = 43 (matches given electrons).
• Atomic Symbol w/ Isotope Notation: \( \ce{^{100}_{43}Tc} \).

6. For Lead (Pb²⁺):

• Mass Number: Protons (82) + Neutrons (125) = 207 (matches given mass number).
• Electrons: Charge = +2, so \( e = p - \text{charge} = 82 - 2 = 80 \) (matches given electrons).
• Atomic Symbol w/ Isotope Notation: \( \ce{^{207}_{82}Pb^{2+}} \).
