and fluorine atoms, which show a gradual approximation to a minimum value of 1.30 × 10 –8 cm. The diameters of the inert gases as found in this way are given in the second column of the ...

Normally, a catalyst uses an inert support to stabilize nanometer-sized clusters of metal atoms, or metal nanoparticles. During catalysis, only the surface atoms act as active sites, leaving atoms ...
