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]
The Wooden Spoons Museum (Romanian: Muzeul Lingurilor de Lemn) or Ion Țugui Spoon Museum (Muzeul Lingurilor "Ion Țugui") [1] is a museum in Câmpulung Moldovenesc, in the Suceava County, Romania. It is located in the house where the history professor Ion Țugui lived, [ 2 ] at no. 1 in Gh.

The energy levels in the atom for the single lines are indicated by 1 S 0 1 P 1 1 D 2 1 F 3 etc., and for the triplets, some energy levels are split: 3 S 1 3 P 2 3 P 1 3 P 0 3 D 3 3 D 2 3 D 1 3 F 4 3 F 3 3 F 2. [2] Alkaline earths and mercury also have spectra with similar features, due to the two outer valence electrons. [2]
Double ionization is a process of formation of doubly charged ions when laser radiation or charged particles like electrons, [1] positrons [2] or heavy ions [3] are exerted on neutral atoms or molecules. Double ionization is usually less probable than single-electron ionization. Two types of double ionization are distinguished: sequential and ...
For instance, lithium, atomic number 3, has two electrons in the 1s shell and one in the 2s shell. Because the two 1s electrons screen the protons to give an effective atomic number for the 2s electron close to 1, we can treat this 2s valence electron with a hydrogenic model.
The monomer BH 3 is unstable since the boron atom has an empty p-orbital. A B−H−B 3-center-2-electron bond is formed when a boron atom shares electrons with a B−H bond on another boron atom. The two electrons (corresponding to one bond) in a B−H−B bonding molecular orbital are spread out across three internuclear spaces. [1]
The cubical atom was an early atomic model in which electrons were positioned at the eight corners of a cube in a non-polar atom or molecule. This theory was developed in 1902 by Gilbert N. Lewis and published in 1916 in the article "The Atom and the Molecule" and used to account for the phenomenon of valency. [1]
