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 ...

Researchers have provided a surprisingly simple explanation for the mechanism and features of the "Golgi apparatus" -- a structure that has baffled generations of scientists. The new model developed ...

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 ...

The nucleus is very small compared to the atom as a whole: as electrons are even smaller, most of an atom is empty space the diameter of a nucleus can be 100,000 times less than the diameter of an ...

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 ...

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, ...
