Have you heard about bonds between different atoms?You must be wondering what kind of bonds an atom can form. Well, there are various chemical bonds present between atoms of various compounds.An atom is a minor component of any compound. Our whole world is made up of these tiny particles. You can also consider it as a building block. They are made up of neutrons, electrons, and protons. The number of electrons and protons is equal in an atom. But their number may vary between different types of atoms. The electrons revolve around the nucleus in orbit. The outermost orbit or shell is known as the valence shell, and the electrons present in the valence shell are known as valence electrons. Protons and neutrons are present in the center of the atom. In most of the atoms, the outer shell is not filled, which makes it unstable. To gain stability, they may lose, gain or share their electrons. When two or more atoms share or donate their electrons, they form molecules. This process requires bonding between these atoms, which is known as chemical bonding.To find the answer to why atoms form bonds, please continue to read the article. Read more interesting facts about science and why atoms share electrons in covalent bonds and why things float.What are atoms and bonds?All atoms, except noble gases, form bonds to gain stability. Did you know that the electrostatic attraction between oppositely charged ions is known as the ionic bond?Atoms are the building blocks for all the compounds found in our universe. They are tiny and can be seen only under a microscope. They are made up of neutrons, electrons, and protons. The protons, together with the neutrons, make the central mass of the atom, while the electrons revolve around this central mass in their orbits or shells. The protons are positively charged, and the electron is negatively charged. Since the number of protons and electrons are the same, the atom is neutral in nature. The neutrons determine the mass of the atom.Chemical bonds are a kind of electromagnetic attraction between various atoms and molecules to form more significant compounds. The atoms bond together by sharing, losing, or gaining electrons. They do this to attain stability. Stable atoms are those which have completely filled valence shells.What are the different types of atom bonds?Basically, two types of bonds are formed between different atoms by giving, taking, and sharing electrons. But did you know that metallic bond is the third reason behind atomic bonds?Two types of atomic bonds are:Covalent bond: This is the strongest type of chemical bond. When two or more atoms share electrons to fill their valence shells and attain stability, they form covalent bonds. Atoms share their electrons in pairs. Since the atom doesn’t lose or gain any electron, there is no charge on the molecule, and it is neutral in nature. The covalent bonds are extremely common in nature and are also found in living organisms.Ionic bond: Atoms may lose or gain electrons to attain stability. When an atom donates its valence electrons to another atom, they form an ionic bond. When an atom gains electrons, the number of electrons becomes more than the number of protons. This results in a negative charge on that atom. Similarly, when an atom donates its valence electrons, the number of protons becomes more than the number of electrons, resulting in a positive charge.Why do most atoms form chemical bonds?The powerful electrical force of attraction between atoms or ions in the structure is called the chemical bond. Almost all the atoms are unstable, except the noble gases. It is necessary for all other atoms to form chemical bonds with other atoms to become stable.A stable atom means that the valence shell of the atom is completely filled. This stability is naturally present only in noble gases, which include helium, neon, argon, krypton, xenon, radon, and oganesson. All the other atoms do not have a completely filled valence shell and hence are unstable. To exist properly, it is extremely important for them to attain stability. They do this by forming bonds with atoms of their own kind like O2 and H2 or with different atoms like CO2, H2O, and many others. The atoms may share, donate or gain electrons to complete their valence shell. There are basically two types of bonds: chemical bonds and ionic bonds.How do atoms bond with one another?If the atom has one or two electrons in its valence shell, it will donate these electrons to an atom that requires one or two electrons to fill its valence shell. Similarly, if an atom has more than five electrons, it is challenging for it to donate such numerous electrons. So, it gains electrons from an atom that can easily donate its own. This kind of exchange of electrons between different atoms results in the formation of ionic bonds. They will have a negative or positive charge on them. For example Na+1, Cl-1, Ca+2, and others.If an electron has four or five electrons in its valence shell, it isn’t easy to donate or gain electrons. So, they share their electrons with another atom that has a similar configuration. Both of them will share their electrons in pairs. This results in the formation of covalent bonds between atoms. It is the most powerful chemical bond and cannot be broken easily, for example, H2, O2, CO2, H2O, and many others.What is the difference between an atom and a molecule?Atoms are the tiniest particle of an element, while the molecule is a group of two or more atoms joined together by a chemical bond.Many atoms (except noble gases) do not exist in a free state. They are not stable and hence need to make a molecule by bonding with another atom. A molecule may be made up of the same or different atoms. There is only a nuclear bond in an atom, while a molecule can have covalent or ionic bonds. An atom constitutes neutrons, protons, and electrons, while a molecule constitutes two or more atoms. The shape of an atom is spherical, while the form of a molecule can be triangular, linear, or angular. Since the atoms are unstable, they are highly reactive, while the molecules are less reactive since their valence shells are completely filled.Is there any atom that does not form any bond with other atoms?Yes, there are few atoms that do not form any bond with other atoms. They are known as noble gases.The noble gases are helium, neon, argon, krypton, xenon, radon, and oganesson. These elements do not react with other atoms and can exist independently. This is because they have completely filled valence shells and do not require sharing, donating, or gaining electrons to attain stability. They are highly unreactive.The valence shells of the lightest two elements, hydrogen, and helium, can hold up to two electrons. As a matter of fact, hydrogen and helium require only two electrons for achieving a stable configuration. For most other elements, the types of bonding and the resulting properties of the elements can vary considerably.Here at Kidadl, we have carefully created lots of interesting family-friendly facts for everyone to enjoy!
