Electron Configuration of Multielectron Atoms

Electron Configuration of Multielectron Atoms

The alkali metal sodium (atomic number 11) has one more electron than the neon atom. This electron must go into the lowest-energy subshell available, the 3s orbital, giving a 1s22s22p63s1 configuration. The electrons occupying the outermost shell orbital(s) (highest value of n) are called valence electrons, and those occupying the inner shell orbitals are called core electrons. Since the core electron shells correspond to noble gas electron configurations, we can abbreviate electron...

Area of Science:

Materials Science
High-Pressure Physics
Computational Chemistry

Background:

Cerium-nitrogen (Ce-N) compounds are explored for novel material properties.
High-pressure synthesis is a key method for discovering new nitrogen-rich materials.

Purpose of the Study:

To investigate the structural, dynamical, and electronic properties of Ce-N compounds under high pressure.
To identify stable and metastable Ce-N phases with potential energetic applications.

Main Methods:

High-throughput computational screening.
Density Functional Theory (DFT) calculations.
Phonon and elastic stability analyses.

Main Results:

Prediction of four Ce-N phases: I41/a-CeN4, R3̅m-CeN6, P6mm-CeN14, and P6mm-CeN17.
Identification of polymeric nitrogen structures including helical chains, N6 rings, and layered molecular sieves.
I41/a-CeN4 is quenchable to ambient conditions with thermal stability up to 500 K.
P6mm-CeN14 is dynamically and mechanically stable at ambient pressure.
Electronic properties reveal significant charge transfer contributing to ionic (Ce-N) and covalent (N-N) bonding.
P6mm-CeN14 exhibits the highest energy density (8.45 kJ/g) and explosive performance among metal polynitrides.

Conclusions:

Ce-N compounds can form stable and metastable phases with diverse polymeric nitrogen structures.
The layered molecular sieve P6mm-CeN14 represents a new record for high-energy metal polynitrides.
Understanding charge transfer mechanisms is crucial for designing stable energetic materials.
