Concept explainers
Interpretation:
The Lewis structure for each of the given ions and molecules is to be explained.
Concept introduction:
The structure used to show the bonding between the atoms and a lone pair of electrons of amolecule is known as Lewis structure.
The rules for drawing the Lewis structure areas follows:
The skeletal structure of the compound is drawn, in which theelement with thelowest electronegativity is placed as thecentral atom, which is surrounded by the substituent atoms.
The total number of valence electrons for the compound is determined.
Subtract two electrons for each bond in the skeletal structure from thetotal number of valence electrons to know the remaining number of electrons.
Complete the octet of each terminal atom by placing a pair of electrons from the remaining electrons.
If any of the electrons are remaining after completing the octets of the terminal atoms, place the remaining electrons as a pair on the central atom.
