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

Imidazoles and triazoles are essential chemical compounds used in many medicines, including drugs used to defeat various pathogen-induced infections and cancer. Besides these applications, both ...

Derived by English mathematician John Wallis in 1655, the original formula calculates pi as the product of an infinite series of ratios – it has now emerged from a solution of physicist Niels Bohr’s ...

If a single, solitary atom of anti-hydrogen annihilated in the room you're in, would you notice anything? Would it be bad for you?

This breakdown of the Standard Model of Particle Physics covers everything from the discovery of the subatomic particle to the naming of a "quark." ...

The Bohr model is a neat but quite imperfect depiction of the inner workings of an atom before things got too muddled up by quantum principles.

Researchers orbit a muon around an atom, confirm physics is broken The proton's charge radius shouldn't change, and yet it appears to.

An atom of antihydrogen has had its spectrum measured with a powerful laser. Luckily for the standard model, it seems to match its hydrogen counterpart ...

Greene “with that beautiful blonde hair is driving down the highway in a hydrogen car,” he said. “And the problem with a hydrogen car, if something goes wrong, it’s like the atom bomb went ...

Postulates of Bohr’s Model of an Atom are: The electron in the hydrogen atom can move around the nucleus in a circular path of fixed radius and energy.

AN ATOM'S electrons are an ever-shifting quantum melee, but it turns out you can still take their photograph as if they were standing still. A quantum-style microscope has imaged the hydrogen atom ...
