Herein, a series of covalent bonding oxygen-doped carbon nitride/graphitic carbon nitride hybrids (O-CN/CN) have been synthesized via solvothermal treatment using cyanuric chloride, cyanuric acid (derived from hydrolysis of cyanuric chloride) and urea-derived graphitic carbon nitride as precursors. In...
In a Lewis structure of a covalent compound, the shared electron pair between the hydrogen and chlorine ions is represented by a line. The electron pair is called a bonding pair; the three other pairs of electrons on the chlorine atom are called lone pairs and play no direct role in holdin...
The covalent bonding in oxygen gas, nitrogen gas, and hydrogen gas differ from one another in terms of the number of electron pairs that are shared between the atoms, yet each one of these gases is called a "molecular element" and a "diatomic element." ...
Lewis structures and the octet rule jointly offer asuccinctindication of the type of bonding that occurs in molecules and show the pattern of single and multiple bonds between the atoms. There are manycompounds, however, that do not conform to the octet rule. The most common exceptions to the...

Covalent bonding as seen in a hydrogen chloride molecule. The hydrogen atom (H) shares an electron (yellow) with the chloride atom (Cl). co·va·lent bond (kō-vā′lənt) A chemical bond formed when electrons are shared between two atoms. Usually each atom contributes one electron to ...
to that of hydrogen is far more attractive to electrons than both of thehydrogen atomsand it is able to exert a much more powerful pull on the shared electrons than the hydrogen atoms. Theoxygen therefore becomes more negatively chargedas it pulls thebonding pairof electrons closer towards it....
Sometimes atoms have such a strong affinity for electrons that they are able to steal electrons from other atoms (a process called ionic bonding), but most of the time there is not a large enough difference in electronegativity (ΔE−⪅2) for atoms to do this. Instead, atoms will share...
Figure 1. Oxygen molecules orient randomly most of the time, as shown in the top magnified view. However, when we pour liquid oxygen through a magnet, the molecules line up with the magnetic field, and the attraction allows them to stay suspended between the poles of the magnet where the ...
