Identify one advantage to each of the following models of electron configuration: dot structures arrow and line diagrams written electron configurations

A Lewis dot structure is simple and shows clearly the number of valence electrons in an atom.

Arrow and line diagrams show the spin direction of electrons as well as every orbital.

Written electron configurations are compact and also show the distribution of electrons between sublevels.

Electron configuration can be defined as the arrangement of electrons within the orbitals shells and subshells of an atom.

In Lewis dot structures, valence electrons are represented as dots around the atom arranged in pairs.

A Lewis dot structure is simple and shows clearly the number of valence electrons in an atom

Arrow and line diagrams or orbital diagrams use boxes and arrows to represent the electron configuration of atoms, showing the individual orbitals and the pairing arrangement of electrons.

One advantage of this model is that it shows the spin direction of electrons as well as every orbital.

Written electron configuration notation uses superscripts to indicate the number of electrons in a given sublevel.

One advantage of written electronic configuration is that it is more compact as it eliminates the use of boxes and arrows and it also shows the distribution of electrons between sublevels.
