Pure covalent bonds

Pure covalent bonds

Definition:

• A pure covalent bond is formed when two atoms share a pair of electrons, and these shared electrons are attracted to the positive nuclei of both atoms.

Key Characteristics:

• Pure covalent bonds occur between atoms with the same electronegativities, meaning they have an equal tendency to attract electrons.
• In a pure covalent bond, there is no significant difference in electronegativity between the atoms, resulting in no ionic character in the bond.

Example:

Hydrogen Molecule (H₂):

• Two hydrogen atoms, each with one electron, come together to form a hydrogen molecule (H₂).
• In this molecule, the two hydrogen atoms share their electrons equally, resulting in a pure covalent bond.
• The shared pair of electrons are equally attracted to both hydrogen nuclei, holding the atoms together.

Significance:

• Pure covalent bonds are essential in forming molecules of various elements and compounds.
• They play a crucial role in the structure and stability of molecules.
• Understanding pure covalent bonds helps explain the properties and reactivity of substances in chemistry.
