Take a look in ~ the picture below. Each of those fancy balls is one electron. In an atom, the electron spin approximately the center, likewise called the nucleus. The electrons choose to it is in in different shells/orbitals. Covering number one have the right to only hold 2 electrons, covering two deserve to hold 8, and also for the an initial eighteen elements shell three can hold a maximum of eight electrons. As you learn about elements with more than eighteen electron you will find that shell three deserve to hold much more than eight. Once one covering is full, the next electron the is included has to relocate to the following shell.So... For the facet of SILICON, you already know that the atomic number tells you the variety of electrons. That way there are 14 electrons in a silicon atom. Looking in ~ the picture, you deserve to see there space two electron in shell one, eight in covering two, and also four in shell three.

Silicon DioxideSilicon dioxide is really much favor carbon dioxide (CO2) in the means the electrons are shared. If girlfriend look at the routine table, you"ll view that silicon (Si) is directly listed below carbon (C). When facets are in the very same column, they plot in similar ways. So, silicon creates two double bonds with two separate oxygen (O) atoms. Look in ~ the dot structure to see exactly how the electrons are shared!
