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

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 ...

What lies within the H atom? Experimental observation of the transverse nodal structure of four atomic hydrogen Stark states. The images in the middle show experimental measurements. Interference ...

Scientists at EPFL and AstraZeneca have developed a method to map the atomic-level structure of amorphous drugs, demonstrated on a GLP-1 receptor agonist candidate for diabetes and obesity treatment.

Atomic-scale imaging emerged in the mid-1950s and has been advancing rapidly ever since—so much so, that back in 2008, physicists successfully used an electron microscope to image a single ...

THE GENERAL PICTURE OF THE ATOM. THE present state of atomic theory is characterised by the fact that we not only believe the existence of atoms to be proved beyond a doubt, butalso we even ...

Learn what mass number and atomic number tell us about the protons, neutrons and electrons in science's current Rutherford-Bohr model of an atom.

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 ...

The number of protons in an atomic nucleus defines what element that atom represents. For instance, hydrogen is the universe's lightest element, and it always has one proton in its atomic nucleus.

Achieved the first spectroscopic observation of hydrogen (H 2) and deuterium (D 2) molecules physically adsorbed within an atomic-scale space known as a picocavity.
