Covalent Bond Ionic Bond Hydrogen Bond
Between heaven and earth, everything is formed by the combination of various forces. The structure of matter has the genus of covalent bonds, ionic bonds, and hydrogen bonds. These three are the key to the formation of matter.
In covalent bonds, two atoms are connected by a common pair of electrons, like glue and paint, sharing electrons to form a stable state. Atoms produce electrons and blend with each other, as if they work together to build the foundation of matter. Its force makes atoms closely interdependent, forming the structure of molecules, or the lightness of gases, or the stability of solids, all depend on the force of this bond.
Ionic bonds are different. Anions and cations, due to the attraction of electric charges, approach each other and eventually combine. Cations lose electrons and become positively charged. Anions gain electrons and become negatively charged. Positive and negative attraction, such as the phase of a magnet, forms ionic compounds. The force of this bond makes the substance unique. In water or in the molten state, ions can move freely, so they can conduct electricity, which is very different from what is formed by covalent bonds.
Hydrogen bonds, although not traditional chemical bonds, should not be underestimated. After hydrogen atoms are connected to electronegative atoms (such as nitrogen, oxygen, and fluorine), because the electron cloud of hydrogen is biased towards other atoms, hydrogen is positively charged, and can attract each other with another electronegative atom to form a hydrogen bond. This bond plays a key role in maintaining the structure of biological macromolecules, such as the characteristics of water and the configuration of proteins and nucleic acids. Water has a high boiling point and a high specific heat capacity due to hydrogen bonds, which allows life to survive in a suitable environment; proteins and nucleic acids form a specific three-dimensional structure due to hydrogen bonds in order to perform their biological functions.
Covalent bonds, ionic bonds, and hydrogen bonds, each performing their duties, in the microscopic world, weaving a complex network of substances, so that all things in the world have different shapes and properties, forming a wonderful scene of the universe.
