Take a look at the picture below. Each of those fancy balls is an electron. In an atom, the electron spin roughly the center, additionally called the nucleus. The electrons prefer to be in separate shells/orbitals. Shell number one deserve to only hold 2 electrons, covering two deserve to hold 8, and for the first eighteen aspects shell three deserve to hold a best of eight electrons. As you learn around elements with an ext than eighteen electrons you will discover that covering three have the right to hold much more than eight. As soon as one shell is full, the next electron that is included has to move to the following shell.So... For the aspect of SILICON, you already know the the atomic number tells you the number of electrons. That means there room 14 electron in a silicon atom. Looking in ~ the picture, you can see there space two electrons in shell one, eight in shell two, and also four in shell three.

Silicon DioxideSilicon dioxide is an extremely much prefer carbon dioxide (CO2) in the means the electrons are shared. If you look in ~ the routine table, you"ll check out that silicon (Si) is directly listed below carbon (C). When facets are in the very same column, they act in similar ways. So, silicon creates two double bonds through two separate oxygen (O) atoms. Look at the dot framework to see just how the electrons are shared!
