https://www.liacoseducationalmedia.com. • This video is a short excerpt from Shedding Light on Atoms Episode 4: The Periodic Table, part of the Shedding Light on Atoms series which documents the development of our ideas about atoms while at the same time teaching students everything they need to know about modern chemistry. • In this Episode, we begin by showing students that elements can, at a simple level, be classified into metals and non-metals. • We look at how the invention of the first battery in the year 1800 soon led to the discovery of many new elements, and at how aluminium (or aluminum) is still made using electricity today. • We then explain how, in the late 1860s, Dmitri Mendeleev devised the first Periodic Table which organised the then-known elements into groups based on how they behave chemically. • We finish by describing how he was able to predict not just the existence of many elements that hadn’t been discovered, but also many of their properties as well. • The worksheet for students and the video's script can be seen on our website at • https://www.liacoseducationalmedia.com.
