A covalent bond is formed by the equal sharing of electrons from both participating atoms. The pair of electrons participating in this type of bonding is called a shared pair or bonding pair. Covalent bonds are also called molecular bonds. Sharing of bonding pairs will ensure that the atoms achieve stability in their outer shell, which is similar to the atoms of noble gases.
A covalent bond is a type of chemical bond formed between atoms by the sharing of electrons. In a covalent bond, two atoms share one or more pairs of electrons to achieve a stable electron configuration, usually resembling the noble gas configuration.
### Key Features of Covalent Bonds:
1. **Electron Sharing:** Covalent bonds occur between non-metallic elements that have similar electronegativities. These atoms share electrons to attain a more stable state.
2. **Single, Double, or Triple Bonds:** Atoms can share one, two, or three pairs of electrons, resulting in single, double, or triple covalent bonds, respectively.
3. **Bond Length and Strength:** The strength of a covalent bond depends on the number of shared electron pairs. Generally, multiple bonds are shorter and stronger than single bonds.
4. **Molecular Shapes:** Covalent bonding influences the shapes of molecules, determining their geometry and properties.
5. **Examples:** Covalent bonds are found in many molecules, such as H2 (hydrogen gas), H2O (water), CH4 (methane), CO2 (carbon dioxide), and O2 (oxygen gas).
The concept of covalent bonding explains how non-metallic atoms combine to form molecules by sharing electrons, creating stable structures.

A present for you ;)
In silent echoes of the heart's refrain,
Words tremble in the chambers of my soul,
Yet in the hush, love's melodies remain,
Unspoken verses, in my heart's console.
A muse, a song unsung, in reverie,
Your name, a sonnet woven in each line,
But fear and doubt, a veil o'er what could be,
So love, unvoiced, in quiet depths, entwine.
For in this dance of longing and of grace,
Whispers unspoken paint our love's embrace.
