(a)
Interpretation:
The formula of the polyatomic ion needs to be determinedhaving 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.
Answer to Problem 15QAP
Explanation of Solution
Given Information:
The molecule is Cl2.
Here thetotal valence electrons are:
Bond pair electrons are obtained as:
