Shell model — In nuclear physics, the nuclear shell model is a model of the atomic nucleus which uses the Pauli principle to describe the structure of the nucleus in terms of energy levels. The model was developed in 1949 following independent work by several… … Wikipedia
Atomic orbital — The shapes of the first five atomic orbitals: 1s, 2s, 2px, 2py, and 2pz. The colors show the wave function phase. These are graphs of ψ(x,y,z) functions which depend on the coordinates of one electron. To see the elongated shape of ψ(x,y,z)2… … Wikipedia
Atomic nucleus — A figurative depiction of the helium 4 atom with the electron cloud in shades of gray. In the nucleus, the two protons and two neutrons are depicted in red and blue. This depiction shows the particles as separate, whereas in an actual helium atom … Wikipedia
Atomic radius — Diagram of a helium atom, showing the electron probability density as shades of gray. The atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the nucleus to the boundary of the… … Wikipedia
Nuclear shell model — In nuclear physics and nuclear chemistry, the nuclear shell model is a model of the atomic nucleus which uses the Pauli exclusion principle to describe the structure of the nucleus in terms of energy levels.[1] The first shell model was proposed… … Wikipedia
Electron shell — Periodic table with electron shells An electron shell may be thought of as an orbit followed by electrons around an atom s nucleus. The closest shell to the nucleus is called the 1 shell (also called K shell ), followed by the 2 shell (or L shell … Wikipedia
World of Ghost in the Shell — The anime and manga series Ghost in the Shell takes place in a cyberpunk version of Earth in the near future. The series focuses on Japan but several other nations figure prominently in some stories. The world of Ghost in the Shell features… … Wikipedia

HISTORICAL SURVEY: THE STATE AND ITS ANTECEDENTS (1880–2006) — Introduction It took the new Jewish nation about 70 years to emerge as the State of Israel. The immediate stimulus that initiated the modern return to Zion was the disappointment, in the last quarter of the 19th century, of the expectation that… … Encyclopedia of Judaism
