The headquarters is located in the History Museum (Romanian: Muzeul de Istorie din Suceava), in the center of Suceava. The History Museum is the oldest part of the Bukovina Museum and essentially the nucleus around which the complex with its various facilities was built. The History Museum was built in 1898 and is now a cultural heritage site. [2]
In chemistry and atomic physics, an electron shell may be thought of as an orbit that electrons follow around an atom's nucleus.The closest shell to the nucleus is called the "1 shell" (also called the "K shell"), followed by the "2 shell" (or "L shell"), then the "3 shell" (or "M shell"), and so on further and further from the nucleus.
Charles Rugeley Bury (29 June 1890 – 30 December 1968) was an English physical chemist who proposed an early model of the atom with the arrangement of electrons, which explained their chemical properties, alongside the more dominant model of Niels Bohr. In some early papers, the model was called the "Bohr-Bury Atom".
Bukovina's population was historically ethnically diverse. Today, Bukovina's northern half is the Chernivtsi Oblast of Ukraine, while the southern part is Suceava County of Romania. [2] Bukovina is sometimes known as the 'Switzerland of the East', given its diverse ethnic mosaic and deep forested mountainous landscapes. [5] [6] [7]
The modern model of the atom describes the positions of electrons in an atom in terms of probabilities. An electron can potentially be found at any distance from the nucleus, but, depending on its energy level and angular momentum , exists more frequently in certain regions around the nucleus than others; this pattern is referred to as its ...
[2] [3] Nicholson was also the first to create a nuclear and quantum theory that explains spectral line radiation as electrons descend toward the nucleus, identifying hitherto unknown solar and nebular spectral lines. [4] [5] Niels Bohr quoted him in his 1913 paper of the Bohr model of the atom. [6]
This work led him to a series of articles in 1965 about the problem of scattering with classical approximation of dynamics of the electrons. The first three papers in 1965 [5] [6] developed a model electron scattering from atoms based on an empirical form for the velocity of electrons in the atom. [7]
In this way, the electrons of an atom or ion form the most stable electron configuration possible. An example is the configuration 1s 2 2s 2 2p 6 3s 2 3p 3 for the phosphorus atom, meaning that the 1s subshell has 2 electrons, the 2s subshell has 2 electrons, the 2p subshell has 6 electrons, and so on.
