It oxidises to BaO 2 by formation of a peroxide ion ([O−O] 2−, or O 2− 2) — with the same charge of O 2−, and therefore keeping the electrochemical balance with the most stable Ba 2+. Using the Kröger-Vink notation, ½ O 2 (g) + O 2– O ⇌ [O 2] 2– O. where J O is the species J in the oxygen position within the rock-salt lattice.
Barium peroxide is an inorganic compound with the formula Ba O 2.This white solid (gray when impure) is one of the most common inorganic peroxides, and it was the first peroxide compound discovered.
Tie up loose ends. Two Lewis structures must be drawn: Each structure has one of the two oxygen atoms double-bonded to the nitrogen atom. The second oxygen atom in each structure will be single-bonded to the nitrogen atom. Place brackets around each structure, and add the charge (−) to the upper right outside the brackets.
For a diatomic molecule, an MO diagram effectively shows the energetics of the bond between the two atoms, whose AO unbonded energies are shown on the sides. For simple polyatomic molecules with a "central atom" such as methane (CH 4) or carbon dioxide (CO 2), a MO diagram may show one of the identical bonds to the central atom. For other ...

(a) The dot-and-cross diagram of the simplified LDQ structure of digermyne. The nuclei are as indicated and the electrons are denoted by either dots or crosses, depending on their relative spins. The ellipse in the centre indicates the relative disposition of the electrons around the germanium-germanium internuclear axis.
The term, "molecular model" refer to systems that contain one or more explicit atoms (although solvent atoms may be represented implicitly) and where nuclear structure is neglected. The electronic structure is often also omitted unless it is necessary in illustrating the function of the molecule being modeled.
The formal charge of any atom in a molecule can be calculated by the following equation: = where V is the number of valence electrons of the neutral atom in isolation (in its ground state); L is the number of non-bonding valence electrons assigned to this atom in the Lewis structure of the molecule; and B is the total number of electrons shared ...
