Detailed explanation-1: -A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms. These electrons are simultaneously attracted by the two atomic nuclei. A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions.
Detailed explanation-2: -Covalent bond is formed by sharing of electrons between the atoms.
Detailed explanation-3: -There are primarily two forms of bonding that an atom can participate in: Covalent and Ionic. Covalent bonding involves the sharing of electrons between two or more atoms. Ionic bonds form when two or more ions come together and are held together by charge differences.
Detailed explanation-4: -Five examples of covalent bonds are hydrogen (H₂), oxygen (O₂), nitrogen (N₂), water (H₂O), and methane(CH₄). 2. What is a covalent bond? A chemical bond involving the sharing of electron pairs between atoms is known as a covalent bond.
