Band theory of solid:
Consider that the Si or Ge crystal contains N atoms. Electrons of each atom will have discrete energies in different orbits. The electron energy will be same if all the atoms are isolated, i.e., separated from each other by a large distance. However, in a crystal, the atoms are close to each other (2 Å to 3 Å) and therefore the electrons interact with each other and also with the neighbouring atomic cores. The overlap (or interaction) will be more felt by the electrons in the outermost orbit while the inner orbit or core electron energies may remain unaffected. Therefore, for understanding electron energies in Si or Ge crystal, we need to consider the changes in the energies of the electrons in the outermost orbit only. For Si, the outermost orbit is the third orbit (n = 3), while for Ge it is the fourth orbit (n = 4). The number of electrons in the outermost orbit is 4 (2s and 2p electrons). Hence, the total number of outer electrons in the crystal is 4N. The maximum possible number of outer electrons in the orbit is 8 (2s + 6p electrons). So, out of the 4N electrons, 2N electrons are in the 2N s-states (orbital quantum number l = 0) and 2N electrons are in the available 6N p-states. Obviously, some p-electron states are empty. This is the case of well separated or isolated atoms.
Q. The maximum possible electrons in an orbit is:
  • a)
    8 (2s + 6p electrons)
  • b)
    8 (6s + 2p electrons)
  • c)
    8 (4s + 4p electrons)
  • d)
    8 (1s + 7p electrons)

Understanding Maximum Electrons in an Orbit
The maximum number of electrons that can occupy an atomic orbital is determined by the quantum mechanical model of the atom.
Electron Configuration Overview
- Electrons are arranged in atomic orbitals, which are defined by quantum numbers.
- The outermost electrons in atoms play a crucial role in chemical properties and bonding.
Significance of 2s and 6p Electrons
- In the context of silicon (Si) and germanium (Ge):
- For Si, the outermost orbit consists of 3s and 3p orbitals.
- For Ge, the outermost orbit comprises 4s and 4p orbitals.
- The maximum capacity for each type of orbital is:
- 2 electrons can occupy the s-orbital (2s).
- Up to 6 electrons can occupy the p-orbitals (6p).
Calculation of Maximum Electrons
- For the outermost shell:
- 2 electrons from the 2s orbital.
- 6 electrons from the 6p orbitals.
- Therefore, the total number of electrons that can fit in the outermost shell is:
- 2 (from 2s) + 6 (from 6p) = 8 electrons.
Conclusion
- The correct answer is option A: 8 (2s + 6p electrons).
- This configuration highlights the stability and bonding characteristics of Si and Ge in solid-state physics. Understanding this helps in grasping the band theory of solids and the behavior of electrons in crystalline structures.

Read the passage given below and answer the following questions:The crystal field theory (CFT) is an electrostatic model which considers the metal-ligand bond to be ionic arising purely from electrostatic interactions between the metal ion and the ligand. Ligands are treated as point charges in case of anions or dipoles in case of neutral molecules. The five d orbitals in an isolated gaseous metal atom/ion have same energy, i.e., they are degenerate. This degeneracy is maintained if a spherically symmetrical field of negative charges surrounds the metal atom/ ion. However, when this negative field is due to ligands (either anions or the negative ends of dipolar molecules like NH3 and H2O) in a complex, it becomes asymmetrical and the degeneracy of the d orbitals is lifted. It results in splitting of the d orbitals.The following questions are multiple choice questions. Choose the most appropriate answer:Q.
