Use the animation to show students a ball model of a water molecule (H 2 O) and post the water molecule card. Explain that a water molecule has two hydrogen atoms and one oxygen atom. Ask students to ...

In the water molecule, the oxygen and hydrogen atoms share electrons in covalent bonds. There are a total of 10 protons and 10 electrons, so the water molecule is neutral. The electron cloud model ...

These trends match our recent experience advising on hydrogen matters. One green hydrogen pathway is evolving to take the ...

Those behind the Extreme E offroad racing series are set to launch its successor, the Extreme H series, later this year. The ...

Each water molecule is made from two hydrogen atoms chemically bonded to ... Image caption, A ball-and-stick model of methane Molecules can be drawn in different ways. In this diagram of methane ...

By pinning down the berkelium atom, the team could test its electronic structure model using ultraviolet ... resulting organometallic molecule reveals the berkelium atom is held in place by two rings ...

Splitting water molecules takes more energy than calculations suggest, and is a key roadblock to cheap hydrogen fuel production. Now, scientists have discovered why.

scientists combined the berkelium metal with an organic molecule containing only carbon and hydrogen to create a chemical reaction. Principal investigators Stefan Minasian, left, and Polly Arnold ...
