What are Periods and Groups in the Periodic Table? | Chemistry | The Fuse School
What's the difference between periods and groups in the Periodic Table and why are the elements structured this way. Find out in this video from the Properties ...
+TriNitY5051 It's shorthand notation for Li - Lithium. He's saying that Lithium - which would be 1s^2 2s^1, contains the electron configuration for He within (or 1s^2). So in shorthand, he's writing [He] 2s^1, and in this way you can shorten up any of these electron configurations. For instance, if you want to write out the electron configuration for Na (sodium) in this manner, you may begin with Neon [Ne] and add the part that makes sodium different from neon [or the 3s^1]. Altogether, it would look like [Ne] 3s^1.

+ocin simat No, Fe has 2 valence electrons. Why? Because the most outer shell for the transitional metals is the "P" shell. Meaning simply they all have 2 valence electrons. Does this make sense?
+ocin simat ye fe has 2 valence electron you are right...

Your videos are great....short and to the point. The videos are perfect for
my 8th grade students. They are a fun way to transition into class, to use
as an engagement piece, or to reinforce a difficult concept. Keep up the
good work.....hope to see more in the future. I appreciate all your efforts!
Geez! It's Been 30 years since I took Chemistry under the Greats Karl
Benson (PUHS: Central High) and Jack Cemming (CVDECS Chelmsford). Your song
brought back some memories! And recalled some knowledge! Thank you!
WOOHOO thank you so much!!! I've been collecting all the Youtube songs on
the Periodic Table and teaching them to my grand kids, this one is one of
my Favorites!! Thank you Sharon Cash from NC
last year in 7th grade my teacher had us listen to the energy song and
still a year later I am watching your videos and learning... thank you for
everything!!
