Why do atoms combine to form molecules? The quantum mechanics of chemical bonds and chemistry....

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...

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...

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...

Your body has all sorts of complicated processes going on, and a lot of them are carried out by incredibly powerful molecules. We're not talking nutrients -- we're talking about 5 of the molecules that keep you ticking!

Chemical bonding explains how atoms combine to form molecules. It involves forces like ionic, covalent, and metallic bonds that hold atoms together, dictating the physical and chemical properties of substances.

Group 14 elements are carbon (C), silicon (Si), germanium (Ge), tin (Sn), and lead (Pb). Their valence electron configuration is unique and is shown by the symbol ns²np². This set-up shows that there are two electrons in the...

The gauge bosons of the standard model of particle physics are responsible for 3 of the 4 known forces in the universe. A force is conferred is through the exchange of virtual bosons. So for example in...

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...

Upon viewing the Investigating Mixtures, Solutions, Elements, and Comnpunds video series, students will be able to do the following: Understand that everything we see, touch, and even things we can't see are made up of matter. Understand...

How non-metal elements combine by covalent bonds to form compounds. Chemistry - Atoms And Bonding - Learning Points. Covalent bonds occur between non-metal atoms. The number of bonds depends on how many electrons are in the outer shell....

Bill Nye explains how atoms combine to form molecules in this fascinating program. With more than 16 Emmys® to its credit and legions of fans, it's easy to see why the "Bill Nye the Science Guy" show is one of the most popular...

This program covers part 3 of the very important topic of the atomic theory of matter. We discuss how atoms combine together to form new compounds. Students review the law of conservation of mass and how the mass of the substances at the...

Resonance requires specific conditions for electron delocalization. The molecule must have a conjugated system with alternating single and double bonds, and atoms must be capable of sharing electrons. Acetamide and the carbonate ion are...

SUMMARY

In this video, I show Why Some Reactions EXPLODE and Others COOL: Root Cause of Chemical EnergyI I show how the chemistry behind endothermic and exothermic reactions can be traced to the underlying quantum...

When two molecules of hydrogen combine with one molecule of oxygen, they undergo a chemical reaction to produce two molecules of water—and also release a lot of energy. This reaction is, therefore, exothermic in nature. Hydrogen is...

All the magic that we know is in the transfer of electrons. Reduction (gaining electrons) and oxidation (the loss of electrons) combine to form Redox chemistry, which contains the majority of chemical reactions. As electrons...

It describes linear combination of atomic orbitals, conditions for combination of atomic orbitals, types of molecular orbitals and energy level diagram.

Learn the basics about covalent bonds, when learning about properties of matter. When similar atoms react, like non-metals combining with other non-metals, they share electrons. This is covalent bonding. Non-metals have shells of...

In this video, students learn about the concept of compounds and how they are formed by the chemical combination of two or more elements. The example of water is used to illustrate how molecules, which are the smallest particles of a...

This video covers how to find the 'relative formula mass', which is the sum of the relative atomic masses of all the atoms within a molecule or compound. It also covers how to find the the percentage mass of a particular element in a...

“Matter: How Do Scientists Use It to Create Technologies?” introduces atomic theory to explore how matter interacts and combines to form new and useful things.
