Which type of model best represents simple molecules?
2 answers:
The correct answer is Lewis dot.
A Lewis dot structure of a molecule is a structure in which the valence electrons of the molecule are represented using dots.
It is usual to seek a simple representation for simple molecules that explains in part, the properties of the molecule.
Such a representation must show the valence electrons in the molecule. A simple representation that can do this is the Lewis dot structure of molecules. The Lewis dot structure of NO2 molecule is shown in the image attached to this answer.
It was introduced by G.N Lewis and can be successfully used to represent many simple chemical molecules.
