New ReviewThis video uses colorful imagery and animations to illustrate how matter is made of tiny particles. The nature of atoms and molecules is explored through instructive imagery. The video correlates to the Next Generation Science Standard...

Atoms are the basic building blocks of all matter and they are very very small. They are made up of protons, neutrons and electrons and they are the smallest unit of matter that still retains the basic properties 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...

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

In this video, we'll be talking about how to determine the number of protons, neutrons, and electrons in an ion. We'll be using the periodic table to help us out, so don't miss it!

A molecule is nearly all empty space, apart from the extremely dense nuclei of its atoms and the clouds of electrons that bond them together. When that molecule forms, it arranges itself to maximize attraction of opposite charges and...

In the first physical science video for the Next Generation Science Standards Paul Andersen explains the structure and properties of matter. He starts by explaining how all matter is made of about 100 smaller particles called matter. ...

In this video Paul Andersen explains how the photons emitted from or absorbed by an atom or nuclei is directly related to electrons moving between energy level. Absorption and emission are a direct result of the conservation of energy....

In this video Paul Andersen describes the positive force intermolecular forces found between all atoms and molecules. As electrons are distributed unevenly it creates instantaneous dipoles which hold molecules together. This force even...

Hank bursts our ideal gas law bubble, er, balloon, and brings us back to reality, explaining how the constants in the gas law aren't all that constant; how the ideal gas law we've spent the past two weeks with has to be corrected...

Atoms for kids is an introduction video that helps students learn all about atoms. We answer questions like "What is an Atom?", "What is an Atom made of?", and "What do Atoms do?". We explore protons, electrons and neutrons and give a...

Learn the basics about Atomic Mass Units. The atomic mass is used to find the average mass of elements and molecules and to solve stoichiometry problems. Find out more in this video!

What is an atom? And what is it made of? In this video, I will be introducing you to the atom. We will also look at concepts like atomic mass, elements and isotopes.

Learn the basics about Atomic Mass Units. The atomic mass is used to find the average mass of elements and molecules and to solve stoichiometry problems. Find out more in this video!

This video is on moles and how to convert between grams and moles. The speaker explains what a mole is, its significance in measuring chemical amounts, and the use of Avogadro's constant in determining the number of atoms or molecules in...

Atoms or molecules combine to form a new compound in a synthesis reaction. Examples include the addition of oxygen to magnesium metal to create magnesium oxide and the addition of carbon dioxide to water to crete carbonic acid. A...

SUMMARY:

To make most complex structures in the universe like trees, and us, you need more than atoms. You need molecules. How do you go from atoms formed in the core of stars, to molecules that can lead to living...

What the microscope did to unlock the secrets of biology, the ""chemiscope"" is intended to do, to revolutionize chemistry. The ultimate goal is to observe chemistry in the act, to see the making and breaking of bonds in real-space and...

This video provides an overview of alkenes, a type of hydrocarbon that contains a double carbon-carbon bond in their molecules. The video covers the structure and formulas of several alkenes, including ethene, propane, butene, and...

What does our planet look like from space? Most are familiar with the beloved images of the blue marble or pale blue dot -- Earth from 18,000 and 3.7 billion miles away, respectively. But closer to home, within the...

Journey through the fascinating states of matter—solid, liquid, and gas—and discover how atoms and molecules behave in each. This video unravels the atomic-level interactions that define each state, from the tight bonds of solids to...

This video is a lesson on how to represent elements and compounds in terms of the atoms they can take. The video covers the definition of an element, the periodic table, chemical symbols, and formulas. It also explains how compounds are...

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.

We've already learned about different types of chemical bonds, including covalent bonds. But now that we know about enthalpy, and orbitals, and some other concepts, let's revisit the covalent bond and dig a little deeper.
