Question

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:

Orbital notation uses arrows in boxes to represent electrons, where the direction of the arrow indicates electron spin. Dot - structures do not show electron spin.

Answer:

Orbital notation shows the spin of the electrons.
