The heavy metal uranium is, besides its radioactive reputation, known for its intricate chemistry and diverse bonding behaviors. Now, an international team of scientists utilized synchrotron light ...

Valence Shell Electron Pair Repulsion (VSEPR) theory is a cornerstone of chemical understanding, providing insights into molecular geometry by predicting the arrangements of electron pairs around ...

Discover how valence shell electron pair repulsion shapes molecular geometry and influences chemical bonding in chemical engineering processes.

Valence-bond theory describes bonds in terms of overlap of electron waves. The concept of atomic orbital overlap leading to chemical bonding as embodied in valence-bond theory represents a useful tool ...

Their atoms’ outer shells hold three valence electrons and their valence shell electron configuration is defined as ns² orbital notation (where n is the principal quantum number).

We formulate a one-center nonorthogonal configuration interaction singles (1C-NOCIS) theory for the computation of core excited states of an initial singlet state with two unpaired electrons. This ...

Locate the valence shell: Identify the highest principal quantum number (n) within the electron configuration to determine which shell is considered the valence shell. 4. Calculate valence electrons: ...
