The atomic chain reaction theory stated that when a reaction in which free atoms are formed and can decompose molecules into more free atoms which results in a chain reaction.

However, in a more accurate description using molecular orbital theory, the d-like orbitals occupied by the six electrons are no longer identical with the d orbitals of the free atom.

14.
Where ? s, p are the one-electron energies of s-and p-electrons in the free atom and " n " s, p are the number of s-and p-electrons in the valence shell.
15.
A minimum basis set is one in which, on each atom in the molecule, a single basis function is used for each orbital in a Hartree Fock calculation on the free atom.
16.
Whichever species ( ions or atoms ) strike the cathode, collisions within the cathode redistribute this energy until a portion of the cathode is ejected, typically in the form of free atoms.
17.
"' Atomic absorption spectroscopy "'( "'AAS "') is a spectroanalytical procedure for the quantitative determination of chemical elements using the absorption of optical radiation ( light ) by free atoms in the gaseous state.
18.
Based on that idea, modern pseudo-potentials are obtained inverting the free atom Schr�dinger equation for a given reference electronic configuration and forcing the pseudo wave-functions to coincide with the true valence wave functions beyond a certain distance rl _ ..
19.
After a given period, the structure, having an irregular surface that would make it prone to attracting more molecules as a continuation of its current pattern, would capture some of the free atoms and continue to form more of itself to make larger components of nanosensors.
20.
But in a vacuum _ if densities are low enough to avoid condensation and if temperatures can be lowered to near absolute zero _ free atoms can be slowed down to speeds of less than one mile per hour, allowing a close examination of their nature and properties.
