Quanti elettroni di valenza ci sono in un atomo di silicio?
Risposta:
Silicon has four elettroni di valenza.
Spiegazione:
Silicon is element 14 in la tavola periodica
It has two electrons in its first shell, eight electrons in the second shell, and four electrons in the third shell.
Since the electrons in the third shell are the outermost electrons, silicon has four elettroni di valenza.
The video below shows how to use the Periodic Table to determine the number of valence electrons in silicon.
