Number of Electrons Shown in Electron-Dot Structure: 3

The electron-dot structure shows the valence electrons of an atom, which are the electrons in the outermost energy level. In the case of Aluminum (Al), it has a total of 13 electrons, but only 3 of these electrons are valence electrons. These valence electrons are shown as dots surrounding the atomic symbol in the electron-dot structure.
