Electron Configurations. The content that follows is the substance of General Chemistry Lecture 26. In this lecture we continue the discussion of Quantum Numbers and their use in Electron Configurations as well as the relationship of electron configuration to the periodic properties of the elements.
Quantum theory and Einstein's theory of relativity form the basis for modern physics. The principles of quantum physics are being applied in an increasing number of areas, including quantum optics, quantum chemistry, quantum computing, and quantum cryptography.
In chemistry and quantum physics, quantum numbers describe values of conserved quantities in the dynamics of a quantum system. Hence for each system, one must find the answer for a full analysis of the system. A quantized system requires at least one quantum number.
The last quantum number of interest in this context is the spin quantum number, s. This number gives the intrinsic angular momentum (or spin angular momentum or just spin ) of an electron, and is designated by the letter s (the term intrinsic angular momentum simply means that the electron is spinning around its own axis).
Dec 28, 2020 · The research could lead to both higher efficiencies for quantum dot solar cells, and the design of quantum dots compatible with other cell materials, including crystalline silicon.

Quantum computing is expected to power breakthroughs across research disciplines. The Intel Labs quantum computing ecosystem stretches across industry and academia. Third-generation Tangle Lake quantum processors contain 49 superconducting qubits. Ongoing research with QuTech in the Netherlands is solving system-level design challenges.
Quantum physics describes the states of electrons in an atom according to the four-fold scheme of quantum numbers. The quantum numbers describe the allowable states electrons may assume in an atom. To use the analogy of an amphitheater, quantum numbers describe how many rows and seats are available.
-Pauli Exclusion Principle: no two electrons can have the same quantum numbers. An orbital can only hold 0,1, or 2 electrons. The electrons must have opposite spins if there are 2 electrons in the orbital. On the other hand, above ground states are "excited states". These are states with higher energy than the one of the ground state.
