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

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.

This video discusses covalent bonding in chemistry. The presenter starts by explaining that atoms or elements want to have a full outer shell of electrons for stability. They then use examples of how non-metals like fluorine and oxygen...

This program makes the Modern Periodic Table come alive to students. Numerous real-life examples of elements are exemplified in the table. Animations and graphics illustrate concepts not easily achieved through other instructional...

There are 4 main types of carbon-based molecules important to life. They are the building blocks for every living organism on this planet. In this video, I will give you a quick introduction to each type with some fun examples.

Upon viewing the Exploring the Building Blocks of Matter video series, students will be able to do the following: Understand that the quest to better understand the building blocks of matter has transpired over the past several thousand...

For a molecule to exhibit optical activity, it must be chiral, meaning it has no internal plane of symmetry. Additionally, the solution or compound should not contain equal amounts of enantiomers (racemic mixture), as these cancel out...

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...

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.

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...

This video introduces atoms, molecules, and the big bang theory that proposes the creation of matter.

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...

Learn the basics about how atoms bond when learning about the structure of atoms. Bonds form by the attraction of negatively charged electrons and the positive nucleus of atoms. Atoms have a positively charged tiny nucleus which contains...

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.

...

Why does changing just one proton in the nucleus of an atom make a different element? How can a single proton make such a huge difference in an element’s properties?



The simple answer is: The number of...

NOTE: animation error at 2:40 - the periodic table is supposed to be twisted clockwise, and not like it is shown in the video. The twisting enables the element Cs to appear on the extreme left and the element F to appear on the right. In...

The explanation covers the electron configurations, quantum mechanics, and relativistic effects that determine these properties. This video is perfect for anyone curious about the science behind element properties....

Learn the basics about how atoms bond when learning about the structure of atoms. Bonds form by the attraction of negatively charged electrons and the positive nucleus of atoms. Atoms have a positively charged tiny nucleus which contains...

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.

What is the difference between a molecule and a compound? What are the main types of chemical bonds? In this video, we will be answering those questions and more.

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!
