Explanation:
According to the valence shell electron pair repulsion theory, the shape of a molecule depends on the number of electron pairs on the valence shell of the central atom in the molecule.
So, in order to identify the electron domain geometry of a molecule (number of regions of electron density)
1) draw the full Lewis structure of the molecule/ion
2) indicate the electron pairs surrounding the central atom
3) count the number of electron pairs surrounding the central atom
4) decide on the electron pair geometry using valence shell electron pair repulsion theory.
In this exercise we have to use our knowledge of electrons to describe our molecular formula, so we have to:
The valence shell is the outermost shell that an atom can present, that is, it is the shell furthest from the nucleus of an atom.
What is the constitution of electrons?
Electrons are negatively charged particles that revolve around the atomic nucleus and have a mass 1836 times less than that of protons and neutrons. Electrons are particles that are part of the constitution of the atom.
