The Second and Third Periods of the Modern Periodic Table
The modern periodic table is divided into periods, each containing a specific number of elements based on their electron configurations.
Elements in the Second Period
- The second period consists of elements from lithium (Li) to neon (Ne).
- Total elements in this period: 8
- Lithium (Li)
- Beryllium (Be)
- Boron (B)
- Carbon (C)
- Nitrogen (N)
- Oxygen (O)
- Fluorine (F)
- Neon (Ne)
Elements in the Third Period
- The third period includes elements from sodium (Na) to argon (Ar).
- Total elements in this period: 8
- Sodium (Na)
- Magnesium (Mg)
- Aluminum (Al)
- Silicon (Si)
- Phosphorus (P)
- Sulfur (S)
- Chlorine (Cl)
- Argon (Ar)
Combined Total Elements
- When we add the elements from both the second and third periods:
- 8 (Second Period) + 8 (Third Period) = 16 elements
However, the question asks for the total number of elements in just the second and third periods combined, which is 16 elements.
Conclusion
The correct answer to the question about the total number of elements in the second and third periods is option 'A': 16 elements.
