In the following question a statement of Assertion (A) followed by a ...
Assertion: Second period consists of 8 elements.
Reason: Number of elements in each period is four times the number of atomic orbitals available in the energy level that is being filled.
This question is testing the knowledge of the number of elements in a period and the relationship between the number of elements and atomic orbitals in each energy level.
Explanation:
Number of elements in a period:
- The number of elements in a period is determined by the number of atomic orbitals in the energy level being filled.
- Each energy level can accommodate a maximum of 2n^2 electrons, where n is the principal quantum number.
- The first energy level (n = 1) has 2 atomic orbitals (1s and 1p), so it can accommodate a maximum of 2(1)^2 = 2 electrons.
- The second energy level (n = 2) has 4 atomic orbitals (2s, 2p_x, 2p_y, and 2p_z), so it can accommodate a maximum of 2(2)^2 = 8 electrons.
- Therefore, the second period consists of 8 elements.
Relationship between the number of elements and atomic orbitals:
- The number of elements in each period is determined by the number of atomic orbitals available in the energy level being filled.
- The number of atomic orbitals in each energy level can be determined using the formula 2n^2, where n is the principal quantum number.
- Therefore, the number of elements in each period is four times the number of atomic orbitals available in the energy level being filled.
Conclusion:
- Both the assertion and reason are true.
- However, the reason is not the correct explanation of the assertion.
- The correct explanation for the assertion is that the second period consists of 8 elements because the second energy level has 4 atomic orbitals (2s, 2p_x, 2p_y, and 2p_z), which can accommodate a maximum of 8 electrons.
Reason: Number of elements in each period is four times the number of atomic orbitals available in the energy level that is being filled.
