For thousands of years, water was thought to be an element. That is, until some of the greatest chemists in the world managed to crack it open.

Physical Science for Kids is the fun way to learn important facts about physical science and get ready for tests. Take a fascinating journey to the Super Science Station to learn about the elements.

Atomic Models: Centuries ago, people didn’t know exactly what was inside an atom, but they had some “ideas”. Around 400 BC, a Greek philosopher named Democritus came up with a theory that everything in the world was made of tiny...

In this video, we learn about atoms and their subatomic particles - protons, neutrons, and electrons. We also explore how these particles combine to form different elements and how the periodic table is structured. The video provides a...

This video is a lesson on the periodic table of elements. The teacher explains what the periodic table is, how it is organized, and its importance in understanding chemistry. The video covers topics such as the definition of an element,...

In this video Paul Andersen explains how elements and molecules are made of atoms. In a pure sample of a pure substance the average mass remains the same. If more than one atom is found in a molecule the ration of average masses...

In this video Paul Andersen explains how the structure of the nucleus influences the properties of the atom. The number of the protons determines the kind of element. Isotopes are formed when the number of protons remain the same but...

Mr. Andersen details the history of modern atomic theory.

Mr. Andersen describes atomic structure and tours the periodic table.

There are 118 elements on the periodic table, but it seems like only a handful of them get any attention. But just because you haven't heard of an element doesn't mean that it isn't a vital part of everyday life! Learn about these lesser...

It's been said that your body contains billions of atoms from every famous person who ever lived. But is that true? And how do we know?<b<br/>r/>

How do we know what matter is made of? The quest for the atom has been a long one, beginning 2,400 years ago with the work of a Greek philosopher and later continued by a Quaker and a few Nobel Prize-winning scientists. Theresa Doud...

One of the most famous elements in the periodic table doesn't really belong anywhere chemists would like to put it.

Four of the heaviest elements on the periodic table are finally getting names!

Adamantium, bolognium, dilithium. Element Zero, Kryptonite. Mythril, Netherite, Orichalcum, Unobtanium. We love the idea of fictional elements with miraculous properties that science has yet to discover. But is it really possible that...

Scientists have been slowly extending the periodic table one element at a time, pushing to higher and higher masses, and have discovered some incredibly useful materials along the way. But the elements at the current end of the table are...

This week's SciShow news brings you discoveries involving two of the most exotic substances on Earth - the world's rarest element and the world's oldest water. Two great tastes that taste great together? Stay tuned to find out.

Przybylski’s Star has been puzzling astronomers for decades, and it might contain elements or isotopes that scientists have never seen before!

Some works of art can be worth thousands, even millions, of dollars. But what if you aren't so sure that Van Gogh you just bought to hang over your toilet is the real deal? Luckily, we can use science to sniff out fakes!

In this video, we'll explore what atoms and ions are, and what the differences are. We'll also talk about how they're used in chemistry and physical science.

If you're curious about what atoms and ions are, and what the...

In this video, we'll be looking at the different types of notation and how they're used to represent the atomic structure of elements. We'll be using both symbolic and isotope notation to show the different properties of the...

Atoms and Elements: Defining Terms distinguishes the differences between an atom, an element, a molecule, and a compound.
