For a little more than a century, chemists have believed that strong atomic links called covalent bonds are formed when atoms ...

Researchers at Lawrence Livermore National Laboratory (LLNL), in collaboration with the Georgia Institute of Technology, have ...

If you've ever seen a d4 or a caltrop, you've seen the shape of the bond sites on a carbon atom: four equilateral triangles, arranged into a three-faced pyramid with a triangular base. Every ...

A tertiary alcohol is one in which the hydroxyl group is attached to a carbon with no hydrogen atoms attached. This will normally mean that the hydroxyl group is joined to the same carbon atom as ...

It is made from carbon, oxygen, and hydrogen atoms. Carbon dioxide is made from one carbon atom and two oxygen atoms. The molecules of carbon dioxide are thoroughly mixed and dissolved into the water ...

When building an atom, pay close attention to the particles' electrical charges. Protons have a charge of +1. Electrons have a charge of -1. Neutrons are neutral, as its name implies. A stable ...

However, the development of reagents that can selectively introduce a carbon atom is a challenging task. Professor Max ...

Explain that a water molecule has two hydrogen atoms and one oxygen atom. Ask students to use Snap Cubes to make a water molecule. Then show students the animated Snap Cube model of a water molecule.

Covalent bonds, in which two atoms are bound together by sharing a pair of electrons, form the scaffolding that underpins the ...

But what makes oxygen different from carbon? It is the number of protons in the nucleus of an atom that is the defining feature of the atom. It's what makes one element different from another.

Most organic drugs contain one acid group, usually a carboxylic acid, -COOH, or one basic primary, secondary, or tertiary amino group, NC 1-3, [3,22,27,28,29] that determines the acid-base ...
