Explanation:
Electronic configuration is a representation of the distribution of electrons in an atom or ion. It describes the arrangement of electrons in energy levels, sublevels, and orbitals of an atom. By analyzing the given electronic configuration, we can determine the position of the element in the periodic table.
Analyzing the given electronic configuration:
1s^2 2s^2 2p^6 3s^2 3p^6 3d^8 4s^2
We can break down the electronic configuration into different energy levels and sublevels:
- The first energy level (n=1) is filled with 2 electrons in the 1s orbital.
- The second energy level (n=2) is filled with 2 electrons in the 2s orbital and 6 electrons in the 2p orbital.
- The third energy level (n=3) is filled with 2 electrons in the 3s orbital, 6 electrons in the 3p orbital, and 8 electrons in the 3d orbital.
- The fourth energy level (n=4) is filled with 2 electrons in the 4s orbital.
Determining the period:
The period of an element in the periodic table is determined by the highest energy level that contains electrons. In this case, the highest energy level is the fourth energy level (n=4) because it contains electrons (2 electrons in the 4s orbital). Therefore, the element is in period 4.
Determining the group:
The group of an element in the periodic table is determined by the number of valence electrons (electrons in the outermost energy level). In this case, the element has 2 valence electrons, which corresponds to group 2. Therefore, the element is in group 2.
Conclusion:
Based on the given electronic configuration, the element is in period 4 and group 2. Therefore, the correct answer is option (a) Period 4, Group 2.
