:any of more than 100 fundamental substances that consist of atoms of only one kind and that singly or in combination constitute all matter b :one of the distinct parts (as a lens) of a composite device (as a microscope) c :one of the basic constituent units (as a cell or fiber) of...
The Poisson equation is imposed as a proper smoothness condition upon test functions, preserving the power law EZ7/3 for atomic energies and resulting in a proper variational principle. Some generalization is presented for the Poisson equation for equilibrium heat states of atoms. Ab initio energies...
3.1.4 Sup-Generators, Atoms A subset A of a complete lattice L is called sup-generating (resp. inf-generating) if each lattice element can be expressed as a supremum (resp. infimum) of members of A. Such generators can be found if the lattice has atom-like elements. Specifically, an ...

How is the atomic weight of an element determined? Which atomic property is different in each isotope of an element? Carbon has different isotopes. What is different between an atom of 12c and an atom of 13c? Are all atoms of an element identical?
For atoms or ions that are isoelectronic, the number of protons determines the size. The greater the nuclear charge, the smaller the radius in a series of isoelectronic ions and atoms. Variation in Ionization Energies The amount of energy required to remove the most loosely bound electron ...
The lattice of iron with interstitial (i) and substitutional (s) atom in solution can be expected to show a distribution of the i-atoms that depends on that of the s-atoms (fig. 13). A qualitative idea of the sign of Δu can be obtained from the stability of the carbides of the ...
Answer to: Atoms of the same element that have different numbers of neutrons are called ___. A. isotopes B. ions C. isomers D. inert elements By...
On nitriding steels the carbides in the ferrite matrix are gradually transformed into (carbo)nitrides. The carbon atoms released by this transformation can either leave the steel, for example, by CH4 development at the surface, or diffuse deeper into the steel. As formation and desorption of CH4...
The nuclear stability of the atoms can be predicted on the basis of the number of protons and neutrons present in the atom. If the number of neutrons and protons are even in the atom, the are more stable than the atoms having odd protons or neutrons. ...
