Periodic Table Explained: Name Origin

Periodic table explained: video on the name origin - how the periodic table got its name? his video shows how there are 92 naturally occurring elements, one for each kind of atom, and how scientists originally sorted into a list according to their weights of their atoms. Distinct repeating patterns were noticed along this list, from metals to semi-metals to non-metals. Based on these repeating, or periodic, patterns, this list was divided into 7 separate rows of elements that were arranged vertically under each other in a table format. Many notable elements and their properties are shown in this video.

We provide lesson plans, hands-on classroom resources, demonstration equipment, quizzes and a Teacher's Manual to primary school teachers. Animated videos that clearly explain the scientific ideas supports learning by both teachers and students. As a teacher, you don't have to look anywhere else to implement this program. Our work has been verified by science education researchers at the University of Southern Queensland, Dr Jenny Donovan and Dr Carole Haeusler, who confirm that primary students are capable of learning much more complex scientific concepts than previously thought, and crucially, that they love it. Students run to class! The program has been trialed in Australian schools as well as schools in the Philippines, Iran and India. It is conducted as holiday workshops at the Australian Nuclear Science and Technology Organisation, the Queensland Museum as well as the World Science Festival. It has attracted wide media interest, including TV, radio and print, and the research data has been presented at prestigious American Education Research Association and Australian Science Education Research Association conferences. Atomic Theory underlies all the other sciences- genetics, electronics, nanotechnology, engineering and astronomy- so an early understanding will set them up for a more successful learning sequence for all their science subjects, and support their mastery of mathematics as well. We also have extension programs that cover Biology, Physics and Astronomy to an equal depth. About Ian Stuart (Email: [email protected]): The founder of Atomic School, Ian Stuart, taught Chemistry and Physics for 25 years at senior levels before he realized that his 8-year old son, Tom, could understand Atomic Theory at a much deeper level than he expected. After visiting Tom's class at school, he discovered that his peers could also grasp the abstract scientific concepts, as well as apply it usefully to the real world. Ian then developed a program to teach the advanced concepts of high school Chemistry, Physics and Biology to students 10 years younger than they normally would. He found that this engaged their interest in modern science early, and sustained it through to high school and beyond. It also sets them up for future success in their academic and career paths. Ian has a Bachelor's Degree in Chemistry from the University of Queensland and a Master's degree in Electrochemistry from the University of Melbourne.

But how did it get its name? In this video, we'll explain how its 3 key words were chosen. Periodic, Table, and Elements. We'll start with elements. It took thousands of years for scientists to discover all 92 different kinds of atoms that exist. 101.1 Each kind makes a different substance. Because a substance made of only ONE kind of atom is called an element, there are 92 elements in the universe. Scientists made a list using the weights of their atoms, starting with the lightest, hydrogen, to the heaviest uranium. They gave each element its own number showing its place in this list. Scientists called this the Atomic Number. So the Hydrogen must have an Atomic Number of 1, and Uranium an Atomic Number of 92. Later scientists made some heavier atoms in the lab, so the modern list goes up to 118. Scientists noticed something going along the list of elements. The first two elements on the list, Hydrogen and Helium, are both light colourless gases. Although they look alike, when we put a lighted match to Hydrogen, it explodes. But when we light up Helium, it just puts out the flame. We can say that Hydrogen is chemically reactive, whereas Helium is chemically unreactive, or inert. After Helium there's an abrupt change to Lithium which is a soft, shiny metal. Beryllium is a shiny metal too, but a bit harder.
