Figure 7.1 A covalent H-H bond is the net result of attractive and repulsive electrostatic forces. The nucleus-electron attractions (blue arrows) are greater than the nucleus-nucleus and electron-electron repulsions (red arrows), resulting in a net attractive force that holds the atoms together to form an H2 molecule.
Nov 28, 2018 · Carbon has an outer shell consisting of 4 valence electrons. This means it can either add 4 electrons to gain a full outer shell or lose 4 electrons to get rid of its outer shell. Thus, a carbon ion can have a charge of anywhere from -4 to +4, depending on if it loses or gains electrons.

- A Carbon atom has 4 electrons in the outer most Valence shell. so,it requires 4 electrons more to complete it's octet.A carbon atom completes its octet only by sharing its valence electrons with other atoms. As a result, a carbon atom forms four covalent bonds by sharing valence electrons with other atoms.
- The 16 valence electrons fill through the 2 pi bonding orbitals so there is a full double bond between carbon and each oxygen. Oxidation States As you saw above, the total electron count around the atoms in carbon dioxide seriously overestimates the electron density around the carbon atom.
- Valence electrons are the electron’s the atom possesses in its valence shell or the outermost shell of the atom. Atoms have different shells or layers, and each of these layers has its own electrons. However, in chemistry, typically only the electrons within the valence shell can participate in the formation of a chemical bond.

- Aqueous nitrogen may occur in the +5, +3, 0, and -3 valence states. The gases considered are carbon dioxide (CO 2), methane (CH 4), nitrogen (N 2), and ammonia (NH 3). The initial water for this example is defined to be a ground water in equilibrium with calcite at a partial pressure of carbon dioxide of 10-1.5.

(a) Carbon dioxide is made up of carbon and oxygen. We know that the valency of carbon is 4 and that of oxygen is 2. In order for them to combine, we have to balance the valency of 4 of the carbon atom with 2 atoms of oxygen, each of valency 2. Carbon monoxide is a strong reducing agent because it is easily oxidised to carbon dioxide - where the oxidation state is the more thermodynamically stable +4. For example, carbon monoxide reduces many hot metal oxides to the metal - a reaction which is used, for example, in the extraction of iron in a blast furnace.
