Chemical Bonding Flashcards
Define electronegativity
It is the power of an atom to attract electron to itself
Define ionic bond
It is the electrostatic force between oppositely charged ions ( cations and anions)
Define covalent bond
It is the electrostatic force between the nuclei of two atoms and a shared pair of electrons
Define coordinate covalent bond
It is the electrostatic force same as covalent bonding where the shared pair of e- comes from a single atom
Define metallic bond
It is the electrostatic attraction force between positive metal ions and delocalised electrons
Define sigma bond
Sigma bonds are formed by direct overlap of orbitals between the bonding atoms
Define Pi bond
Pi bonds are formed by the sideways of adjacent p orbitals above and below the sigma bond
Define hybridisation
The mixing of s orbitals with p orbitals to form molecular bonds is called hybridisation
Define bond energy
Energy required to break one mole of a particular covalent bond in gaseous state
Define bond length
The intermolecular distance of two covalently bonded atoms
