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 ...

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 ...

For comparison, the radius of a typical bacterium is 1 × 10-6 m and the radius of a human hair is about 1 × 10-4 m.

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 ...

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 ...

A collaborative effort between researchers at the Stanford Synchrotron Radiation Lightsource (SSRL) and the University of California, Davis has resulted in the development of a novel methodology for ...
