Hank gives us a tour of the most important table ever, including the life story of the obsessive man who championed it, Dmitri Mendeleev. The periodic table of elements is a concise, information-dense catalog of all of the...

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...

Atomic Number & Mass Number | Properties of Matter | Chemistry | FuseSchool How do we tell elements apart from each other? Find out in this video from the Properties of Matter chapter of the Virtual School GCSE Chemistry.

Long Jane Silver buys an antique table, despite an old sailor’s warning that it is haunted! Is she ready to discover what lies waiting inside? This lesson will introduce the periodic table of elements and explain how it is...

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 section, I talk about elements, atoms and how they interact. I deal with two types of bonds: Covalent Bonds and Ionic Bonds. I also talk about pH, chemical reactions and metabolism.

In chemistry, we usually talk about atoms and molecules. When we introduce the term 'element', things get a little confusing. In this video, we will cover what an element is in chemistry and give you some examples.

In this educational video, we will explore the differences between atomic number, atomic mass, and mass number in the world of chemistry.

I this video you will see how we can use the periodic table to tell us more about the differences between elements, including the different numbers of protons, neutrons and electrons they possess.

A polyatomic ion is an ion that is made up of multiple elements. Whenever we have a polyatomic ion present, we are not going to change the name at all. The name of the polyatomic ion will stay just as it is. So when we look at the ionic...

Chemists need stoichiometry to make the scale of chemistry more understandable - Hank is here to explain why, and to teach us how to use it.

Hank does his best to convince us that chemistry is not torture, but is instead the amazing and beautiful science of stuff. Chemistry can tell us how three tiny particles - the proton, neutron and electron - come together in...

Today's Crash Course Chemistry takes a historical perspective on the creation of the science, which didn't really exist until a super-smart, super-wealthy Frenchman put the puzzle pieces together - Hank tells the story of how we...

In this episode, Hank welcomes you to the new age, to the new age, welcome to the new age. Here he'll talk about transmutation among elements, isotopes, calculating half-life, radioactive decay, and spontaneous fission....

Learning to talk about chemistry can be like learning a foreign language, but Hank is here to help with some straightforward and simple rules to help you learn to speak Chemistrian like a native.

Organic chemistry is pretty much everywhere! In this episode of Crash Course Organic Chemistry, we’re talking about the amazing diversity among organic molecules. We’ll learn about the origins of organic chemistry, how to write Lewis...

We’ve all heard the phrase “opposites attract.” It may or may not be true for people, but it’s definitely true in organic chemistry. In this episode of Crash Course Organic Chemistry, we’re learning about electronegativity, polarity,...

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...

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

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.

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...
