Definitions Of Three Bondings

Question 1

Nature of metallic bond

Answer 1

electrostatic attraction between a ‘sea’ of negatively charged electrons and positively charged metal ions

Question 2

Nature of covalent bond

Answer 2

electrostatic attraction between the shared electrons and the two nuclei of the bonded atoms

Question 3

Nature of ionic bond

Answer 3

electrostatic attraction holding the oppositely charged ions together

Question 4

Formation of metallic bond

Answer 4

escape of outermost shell electrons from metal atoms

Question 5

Formation of covalent bond

Answer 5

sharing of outermost shell electrons between two atoms
