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 ...

In 2013, physicists used a "quantum microscope" to peer inside a hydrogen atom. Credit: A. S. Stodolna et al., 2013 ...

The team chose the hydrogen atom thanks to its unique properties. “These [hydrogen atoms] are very peculiar…as hydrogen has only one electron, which interacts with the nucleus via a purely Coulombic ...

If you convert the entirety of a hydrogen atom into energy, you get 1.5 x 10-10 Joules, That looks like a very small number, and it is; but gamma radiation is usually bad for you, right?

This is precisely the difference between the new, smaller, dimension of the proton, the nucleus of the hydrogen atom, and the value which has been assumed so far. Instead of 0.8768 femtometres it ...

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 ...

The first direct observation of the orbital structure of an excited hydrogen atom, made using a newly developed "quantum microscope." (Stodolna et al. / Physical Review Letters) Image 2 of 2 ...

An orbital structure is the space in an atom that’s occupied by an electron. But when describing these super-microscopic properties of matter, scientists have had to rely on wave functions — a ...

For a typical hydrogen bond, the spacing between those energy levels would decrease as the atom climbed further up the energy ladder. But instead, the researchers found that the spacing increased.

For example, the oxygen atom has eight electrons, the atom of iron has 26 electrons. Once Bohr tried to use his model to predict the spectral lines of more complex atoms, the results became ...
