Covalent, ionic and metallic bond

The chemical bonds are the connections between atoms of a molecule. These linkages include strong intramolecular interactions. They are related to weaker intermolecular forces, such as dipole-dipole interactions, London scattering forces, and hydrogen bonds. The covalent bond occurs between the two non-metals, the metallic bond occurs between two metals, and the ionic bond occurs between a metal and a non-metal. The covalent bond involves the exchange of electrons, while the metal links have strong attractions and ionic bondsthey involve the transfer and acceptance of electrons from the valence shell. Today in this blog we want to tell you information about the types of links that exist so that you can learn a little more about chemistry and know what characteristics each of these types of links have. So keep reading and enjoying all the information.

What is the covalent bond?

Chemical bonds are the attractive forces that hold atoms together. Bonds are formed when valence electrons, the electrons in the outermost electronic “shell” of an atom, interact. The nature of the interaction between the atoms depends on their relative electronegativity. Atoms with the same or similar electronegativity form covalent bonds, in which the density of valence electrons is shared between the two atoms. Electron density resides between the atoms and is attracted to both nuclei. This type of bond is most often formed between two non-metals.

When there is a greater difference in electronegativity than between covalently bonded atoms, the pair of atoms usually forms a polar covalent bond. Electrons are still shared between atoms, but electrons are not equally attracted to both elements. As a result, electrons tend to be near a particular atom most of the time. Again, polar covalent bonds tend to occur between nonmetals.

What is the ionic bond?

For the atoms with the largest electronegativity differences (such as metals that bond with nonmetals), the bonding interaction is called ionic, and the valence electrons are typically represented as transferred from the metal atom to the nonmetal. Once the electrons have been transferred to the non-metallic, both the metallic and the non-metallic are considered ions. The two oppositely charged ions attract each other to form an ionic compound.

Ionic bonding is the complete transfer of valence electrons between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, while the nonmetal accepts those electrons to become a negatively charged anion. Ionic bonds require an electron donor, often a metal, and an electron acceptor, a nonmetal.

Ionic bonding is observed because metals have few electrons in their outermost orbitals. By losing those electrons, these metals can achieve a noble gas configuration and satisfy the octet rule. Similarly, nonmetals that have about 8 electrons in their valence shells tend to readily accept electrons to achieve the noble gas configuration. In ionic bonding, more than 1 electron can be donated or received to satisfy the octet rule. The charges of the anion and the cation correspond to the number of electrons donated or received. In ionic bonds, the net charge of the compound must be zero.

What is the metallic bond?

Metals form giant structures in which electrons in the outer shells of metal atoms can move freely. The metallic bond is the attractive force between these free-moving (delocalized) electrons and the positive metal ions. Metallic bonds are strong, so metals can maintain a regular structure and generally have high melting and boiling points.

These are formed when the valence electrons of metal atoms are shared by more than one neighboring atom. Metal atoms are held together by a “sea” of electrons floating around. Metals consist of a network of positive ions through which a cloud of electrons moves. Positive ions will tend to repel each other, but are held together by the cloud of negatively charged electrons. Moving electrons, known as conduction electrons, can transfer thermal vibration from one part of the structure to another, that is, metals can conduct heat. They are also good conductors of electricity.

 What are the differences between the covalent, ionic and metallic bond?

There are many types of chemical bonds and forces that join molecules. The two most basic types of bonds are characterized as ionic or covalent. In ionic bonding, atoms transfer electrons to each other. Ionic bonds require at least one electron donor and one electron acceptor. In contrast, atoms with the same electronegativity share electrons in covalent bonds, because neither of the atoms preferentially attracts or repels the shared electrons. Metallic bonds are the chemical bonds that hold atoms in metals together. They differ from covalent and ionic bonds because the electrons in metallic bonds are delocalized, that is, they are not shared only between two atoms. Instead, electrons in metallic bonds float freely through the lattice of metallic nuclei. This type of bond gives metals many unique material properties, including excellent thermal and electrical conductivity, high melting points, and malleability.
