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 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...

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.

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...

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...

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...

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/>

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

Atoms can (and do) bond constantly; it's how they form molecules. Sometimes, in an atomic tug-of-war, one atom pulls electrons from another, forming an ionic bond. Atoms can also play nicely and share electrons in a covalent bond. From...

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.

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...

Mr. Andersen details the history of modern atomic theory.

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

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...

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

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.

In this video, we explore the importance of carbon, an element that is present in everything from the air we breathe to the objects we use daily.

This video provides an overview of the element fluorine, its properties, and its uses. Despite its reactivity, fluorine is used in dental care and pharmaceuticals due to its beneficial effects on teeth and its stable carbon-fluorine...

Let's take a look back at the elements sodium, oxygen, argon, arsenic, and zinc.
