Electron configurations and orbital diagrams can be determined by applying the Aufbau principle (each added electron occupies the subshell of lowest ...
Химические связи
Химические связи
Atoms participate in a chemical bond formation to acquire a completed valence-shell electron configuration similar to that of the noble gas nearest ...
Полярные ковалентные связи
Полярные ковалентные связи
Covalent bonds are formed between two atoms when both have similar tendencies to attract electrons to themselves (i.e., when both atoms have identical or ...

Lewis symbols can be used to indicate the formation of covalent bonds, which are shown in Lewis structures—drawings that describe the bonding in ...
Теория VSEPR
Теория VSEPR
Valence shell electron-pair repulsion theory (VSEPR theory) enables us to predict the molecular structure around a central atom from an examination of the ...

The VSEPR theory can be used to determine the electron pair geometries and molecular structures as follows: Write the Lewis structure of the molecule or ...
Резонансные и гибридные структуры
Резонансные и гибридные структуры
According to the theory of resonance, if two or more Lewis structures with the same arrangement of atoms can be written for a molecule, ion, or radical, ...
Теория валентной связи и гибридизованные орбитали
Теория валентной связи и гибридизованные орбитали
According to valence bond theory, a covalent bond results when: (1) an orbital on one atom overlaps an orbital on a second atom, and (2) the single ...
Теория МО и ковалентная связь
Теория МО и ковалентная связь
The molecular orbital theory describes the distribution of electrons in molecules in a manner similar to the distribution of electrons in atomic orbitals. ...
