Carboxylic acids are ubiquitous in bioactive organic molecules and readily available chemical building blocks. Carboxylic ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I ...

Controlling regioselectivity remains one of the major challenges in hydrocyanation. When an unsymmetrical alkyne undergoes ...

The question of where atoms come from requires a lot of physics to be answered completely – and even then, physicists only have good guesses to explain how some atoms are formed.

Hydrogen Binding Energy Is Insufficient for Describing Hydrogen Evolution on Single‐Atom Catalysts. Angewandte Chemie International Edition , 2025; DOI: 10.1002/anie.202425402 Cite This Page : ...

Make sure students see that each hydrogen atom has 1 proton and 1 electron. Remind students that the electron and its own proton are attracted to each other. Explain that if the atoms get close enough ...

Explain to students that in a hydrogen atom, the negatively charged electron is attracted to the positively charged proton. This attraction is what holds the atom together. Tell students that hydrogen ...

The hydrogen atom — one proton, one electron — loves to hook up with other elements. Hydrogen is an ingredient in molecular matter including methane, vegetable fats salt water, ...

Like ordinary water—H 2 0—each molecule of heavy water contains two hydrogen atoms and one oxygen atom. The difference, though, lies in the hydrogen atoms.
