Concept explainers
Interpretation:
The reason for iodine and sulfur to not have metallic bonds needs to be explained.
Concept introduction:
Delocalized electrons are not present on a single atom or in a covalent bond. One electron pair is called delocalized if it is free to move from one atom to other in a molecule or compound.
Answer to Problem 120A
Iodine and sulfur do not have metallic bonds they can attract the electrons to form a full octet of valence electrons from anywhere which is energetically allowed.
Explanation of Solution
Sulfur is found in 16th group and iodine is found in 17th group. In a lattice of solid state, metals are arranged in such a way that their outer orbitals overlap and their valance electrons are considered delocalized. Iodine and sulfur do not have metallic bonds but they are more attracted towards electrons and take them to form a full octet of valence electrons from anywhere which is energetically allowed.
