Chemical Bonding

Question 1

Define electronegativity

Answer 1

It is the power of an atom to attract electron to itself

Question 2

Define ionic bond

Answer 2

It is the electrostatic force between oppositely charged ions ( cations and anions)

Question 3

Define covalent bond

Answer 3

It is the electrostatic force between the nuclei of two atoms and a shared pair of electrons

Question 4

Define coordinate covalent bond

Answer 4

It is the electrostatic force same as covalent bonding where the shared pair of e- comes from a single atom

Question 5

Define metallic bond

Answer 5

It is the electrostatic attraction force between positive metal ions and delocalised electrons

Question 6

Define sigma bond

Answer 6

Sigma bonds are formed by direct overlap of orbitals between the bonding atoms

Question 7

Define Pi bond

Answer 7

Pi bonds are formed by the sideways of adjacent p orbitals above and below the sigma bond

Question 8

Define hybridisation

Answer 8

The mixing of s orbitals with p orbitals to form molecular bonds is called hybridisation
