Detailed explanation-1: -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 atom preferentially attracts or repels the shared electrons.
Detailed explanation-2: -Ionic and covalent bonds are similar in that they both involve the tiny, negatively charged particles within the atom called electrons. It is the electrons in the outer shell of the atom, called valence electrons, that are involved in both types of bonding.
Detailed explanation-3: -Ionic compounds are elements bonded together through electron-giving. In other words, ionic compounds are ions bonded together in order for the elements to have a full octet.
Detailed explanation-4: -Lewis proposed that an atom forms enough covalent bonds to form a full (or closed) outer electron shell. In the diagram of methane shown here, the carbon atom has a valence of four and is, therefore, surrounded by eight electrons (the octet rule), four from the carbon itself and four from the hydrogens bonded to it.
Detailed explanation-5: -The two main types of chemical bonds are ionic and covalent bonds. An ionic bond essentially donates an electron to the other atom participating in the bond, while electrons in a covalent bond are shared equally between the atoms. The only pure covalent bonds occur between identical atoms.
