Explanation:

To solve this matching problem, we analyze each description using the periodic table rules (period = energy levels, group = column):

1. Alkali metal (Group 1) with 4 energy levels (Period 4)

• Alkali metals: Li, Na, K, Rb, Cs, Fr.
• Period 4 (4 energy levels) → Potassium (K).

2. Alkaline Earth Metal (Group 2) with 2 energy levels (Period 2)

• Alkaline Earth metals: Be, Mg, Ca, Sr, Ba, Ra.
• Period 2 (2 energy levels) → Beryllium (Be).

3. In the boron group (Group 13) and Period 3

• Boron group: B, Al, Ga, In, Tl.
• Period 3 (3 energy levels) → Aluminum (Al).

4. In the carbon group (Group 14) and Period 6

• Carbon group: C, Si, Ge, Sn, Pb.
• Period 6 (6 energy levels) → Lead (Pb).

5. In the nitrogen group (Group 15) and Period 5

• Nitrogen group: N, P, As, Sb, Bi.
• Period 5 (5 energy levels) → Antimony (Sb).

6. In the oxygen group (Group 16) and Period 5

• Oxygen group: O, S, Se, Te, Po.
• Period 5 (5 energy levels) → Tellurium (Te).

7. Halogen (Group 17) with 4 energy levels (Period 4)

• Halogens: F, Cl, Br, I, At.
• Period 4 (4 energy levels) → Bromine (Br).

8. Noble gas (Group 18) with 2 energy levels (Period 2)

• Noble gases: He, Ne, Ar, Kr, Xe, Rn.
• Period 2 (2 energy levels) → Neon (Ne).

9. Halogen with the smallest atomic mass

• Halogens: F (19), Cl (35.5), Br (80), I (127), At (210).
• Smallest atomic mass → Fluorine (F).

10. Alkaline earth metal with the most energy levels (highest period)

• Alkaline Earth metals: Be (Period 2), Mg (3), Ca (4), Sr (5), Ba (6), Ra (7).
• Most energy levels (highest period) → Radium (Ra) (assuming Ra is an option; if not, Ba is next, but Ra has more levels).

11. Transition metal with the smallest atomic mass

• Transition metals: Sc (45), Ti (48), V (51), etc.
• Smallest atomic mass → Scandium (Sc).

Final Matches:

• Alkali metal with 4 energy levels: Potassium
• Alkaline Earth Metal with 2 energy levels: Beryllium
• In the boron group and in period 3: Aluminum
• In the carbon group and in period 6: Lead
• In the nitrogen group and period 5: Antimony
• In the oxygen group and period 5: Tellurium
• Halogen with 4 energy levels: Bromine
• Noble gas with 2 energy level: Neon
• Halogen with the smallest atomic mass: Fluorine
• Alkaline earth metal with the most electron energy levels: Radium
• Transition metal with the smallest atomic mass: Scandium
