To show the electron configuration for an atom, what is the advantage of using an orbital notation compared to a dot structure?
orbital notation takes up less space.
orbital notation shows the spin of the electrons.
orbital notation makes it easier to count the electrons.
orbital notation shows the electron distribution in shells.

Explanation:

The dot structure only shows the valence electrons as dots around the chemical symbol of the element. For instance, the carbon atom has atomic number 6, which means that it has 6 protons and 6 electrons. Four of the 6 electrons are the valence electrons, so the dot structure shows the symbol C with for dots around: each dot is one valence electron.

The orbital notation is a representation of the electron configuration that uses arrows over blanks to represent the electrons. The arrows pointing upward indicate one spin and the arrows pointing downward indicate the other spin (remember that there are only two possible values for the spin quantum number, +1/2 and - 1/2).

Following the example of carbon, you have the following orbital notation:

⇅   ⇅      ↑     ↑      

1s     2s             2p  

That representation shows:

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.
