2D diagram of mellitate C 12 O 6− 12, one of the oxocarbon anions. Black circles are carbon atoms, red circles are oxygen atoms. Each blue halo represents one half of a negative charge. In chemistry, an oxocarbon anion is a negative ion consisting solely of carbon and oxygen atoms, and therefore having the general formula C x O n−
Hydroxide is a diatomic anion with chemical formula OH −.It consists of an oxygen and hydrogen atom held together by a single covalent bond, and carries a negative electric charge.
In chemistry, a hydroxy or hydroxyl group is a functional group with the chemical formula −OH and composed of one oxygen atom covalently bonded to one hydrogen atom. In organic chemistry , alcohols and carboxylic acids contain one or more hydroxy groups.
3) and nitrate (NO − 3) have a trigonal planar structure with π bonding between the central atom and the oxygen atoms. This π bonding is favoured by the similarity in size of the central atom and oxygen. The oxyanions of second-row elements in the group oxidation state are tetrahedral.
Hydrogen atom (center) contains a single proton and a single electron. Removal of the electron gives a cation (left), whereas the addition of an electron gives an anion (right). The hydrogen anion, with its loosely held two-electron cloud, has a larger radius than the neutral atom, which in turn is much larger than the bare proton of the cation ...
The bicarbonate ion (hydrogencarbonate ion) is an anion with the empirical formula HCO − 3 and a molecular mass of 61.01 daltons; it consists of one central carbon atom surrounded by three oxygen atoms in a trigonal planar arrangement, with a hydrogen atom attached to one of the oxygens.
There are many oxides of carbon , of which the most common are carbon dioxide (CO 2) and carbon monoxide (CO). Other less known oxides include carbon suboxide (C 3 O 2) and mellitic anhydride (C 12 O 9). [5] There are also numerous unstable or elusive oxides, such as dicarbon monoxide (C 2 O), oxalic anhydride (C 2 O 4), and carbon trioxide (CO 3).
It consists of one carbon atom surrounded by three oxygen atoms, in a trigonal planar arrangement, with D 3h molecular symmetry. It has a molecular mass of 60.01 g/mol and carries a total formal charge of −2. It is the conjugate base of the hydrogencarbonate (bicarbonate) [8] ion, HCO − 3, which is the conjugate base of H 2 CO 3, carbonic acid.
