Final answer:
The number of electrons shown in electron-dot structures varies depending on the element and its valence electrons.
Step-by-step explanation:
The number of electrons shown in the electron-dot structures depends on the element being represented. In an electron-dot structure, also known as a Lewis structure, the valence electrons of an atom are represented by dots or crosses surrounding the atomic symbol.
For example, in the electron-dot structure for sulfur (S), there would be 6 dots around the atomic symbol. This represents the 6 valence electrons of sulfur.
Therefore, the number of electrons shown in the electron-dot structures varies depending on the element and the number of valence electrons it has.
