A key to learning and studying chemistry is practice. Solving practice problems, working on equations and formulas should be a core feature of your daily study routine. Reviewing and working the ...

Part of Physics (Single Science) Unit 1: Atomic and nuclear physics Most of the mass and all of the positive charge of an atom is in the nucleus. Most of an atom is empty space, (a vacuum). In 1897, ...

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 ...

What you’re looking at is the first direct observation of an atom’s electron orbital — an atom’s actual wave function! To capture the image, researchers utilized a new quantum microscope — an ...

A computational model of the more than 26 million atoms in a DNA-packed viral capsid expands our understanding of virus structure and DNA dynamics, insights that could provide new research avenues and ...

Tough, ultralight foam of atom-thick sheets can be made to any size and shape through a new chemical process. In microscopic images, the foam dubbed "GO-0.5BN" looks like a nanoscale building, with ...
