All-electron calculations of open-shell polyatomic molecules: II. Construction of quasi-localized molecular orbitals in vinyl and formaldiminoxyl radicalsA localization procedure for free radicals using two uni
Owing to the shielding of the 4f shell orbital by the outer 5s and 5p orbitals for Er3+ (ref. 55), the PL wavelength and lifetime of Er3+ in Er–Si QDs exhibit rather weak sensitivity to environmental changes (Supplementary Fig. 5), limiting their use for anti-counterfeiting. Thus, ...
To occupy the same orbital, two electrons must have opposite spins. Hund’s rule: When electrons occupy orbital, one electron enters each orbital until all the orbitals contain one electron. When the orbitals are singly filled, all the electrons have same spin w...
A subshell is made up of a collection of orbitals. Electron shells are subdivided and separated by electron orbitals, resulting in an electron shell subdivision. The first shell is made up of only one subshell, which is the letter’s,’ and the second subshell is made up of two subshells...
3 and so forth and it corresponds to the quantum number in Bohr’s model of the hydrogen atom. If all orbitals have the same value of ‘n’, they are said to be in the same shell ( level ). The total number of orbitals for a given n valu...

Iron (Fe), a transition metal characteristic with an atomic electron configuration of [Ar] 3d64s2, typically presents two oxidation states of Fe²⁺([Ar]3d6) and Fe3+([Ar]3d5). Based on the valence bond theory, the vacant outer shell of 4 s, 4p, and 4d orbitals, along with in...
Answer to: Give all the possible values of the four quantum numbers of an electron in the following orbitals: (a) 3s (b) 4p (c) 3d By signing up,...

Superheavy elements are atoms with more than 104 protons and must be created in laboratories because they do not occur naturally. These elements help scientists test the boundaries of atomic stability and gain insights into nuclear forces. Superheavy elements are located at the far end of the Per...
