(a)
Interpretation:
The formula of the polyatomic ion needs to be determined having similar Lewis structure as the
Concept introduction:
The Lewis structures are used to write a shorthand configuration of number of available valence electrons in an atom for bonding. This structure deals with the magic number 8, and hence, the octet completion is shown by the bonded electrons between the atoms.
This structure is made on basis of octet rule understanding, and it is made sure that the number of electrons surrounding an atom must not divert from the octet.
