So that's the electronĬonfiguration for silicon. These are our P electrons because they're in P orbitals, and then once we're through our 2p6 electrons, we go to 3s2 and we have two more electrons, so it's 3p2. The electron configuration 1s2 2s2 2p6, so as a reminder, theseĪre our S electrons because they're in S orbitals. We're going to talk about and write the configurationĬarbon in the Periodic Table, and we can write its fullĮlectron configuration, just for comparison, so if we start up here, with hydrogen, silicon has That a lot of chemistry, chemical reactions will be driven by other non-noble gases trying And so, since they have aįull octet, they're not very reactive, they have all of the electrons they want, and as a result, you will see in chemistry

Why we call the noble gases noble, and that is because they have a full octet of electrons. So before we get started, I'm just going to remind you If you don't remember what that is, we'll go through a coupleĮxamples right now.

That you normally write electron configurations in. Your other electrons using the same notation And you put that in bracketsĪnd then you write your other electrons, and you write Noble gas that comes right before it, so you go up a row, and you go over to here, where the noble gases live. Immediately preceding? That means we want the It is, you take the noble gas immediately preceding your atom or ion, so what do I mean by So the rule for writing the noble gas notation for something is pretty simple. The transition metals, right here, and the lanthanides, are a little bit more complicated, so we won't be doing that Going to be focusing on examples using main group elements. And to be more specific, in this video we're also We're going to be talking about how you can write electron configurations using noble gas notation.
