sublevel notation shows the electrons and their spins within each orbital. For example the 1s2 electrons would have one arrow pointing up and one arrow pointing down.
You mean valence electron? 2 If your talking about Bohr Diagrams then it depends on the metal

Noble gas notation provides information about the electron configuration of an atom or ion. It indicates the number of electrons in each energy level and the number of valence electrons, which are the electrons in the outermost energy level. This notation helps in understanding the chemical properties and reactivity of an element.
Boron is located in group 3A. It is group 13 in modern notation. This set of elements have three valence electrons.Boron is in the 13th group in the periodic table. Elements in this group has 3 electrons in the outermost energy level. That means they have 3 valence electrons.
Outer electrons
I found out that electron dot diagrams can be helpful because, what if you want to have an easier way to represent the atoms and the electrons in the outer energy level then electron dot diagrams are much easier to use.
It refers to numbers of electrons in the 2p sublevel.

It's important because electrons, specifically valence electrons (the ones in the outer energy level) are the only part of the atom or ion that participates in a chemical reaction.
There are 3 energy levels in chlorine. Look at the shell notation: 2-8-7. So there are 8 electrons in the highest energy level.
These numbers, when referenced in quantum mechanical electron orbital notation note the principle shell (or energy level) of the electrons specified. For example, 1s2 implies that there are two electrons occupying the 1s shell. A 2s shell has a higher energy level than 1s, and so forth. The s designates the geometry of the shell, in this case, spherical.

they are the electrons in the outer shell of the atom(valence electrons)
Each aluminum isotope has 13 electrons. In accordance with the Aufbau Principle those electrons will fill: 1s2, 2s2, 2p6, 3s2, 3p1. The shortcut notation is: [Ne] 3s2, 3p1.
