The phrase "atoms per second" is correct and usable in written English.
It is typically used in scientific contexts to describe a rate of atomic events or processes, such as in physics or chemistry.
Example: "The experiment measured the rate of radioactive decay at 500 atoms per second."
Alternatives: "particles per second" or "molecules per second."
When it didn't have a structure, the rate was about three to five atoms per second.
Being able to observe the material at the atomic scale, they found that the metallic glass would crystallize at a rate of 15 to 20 atoms per second if the liquid formed a structure.
(They have fewer atoms per cubic foot). So if a sound wave was traveling through a big gas cloud in space and we were out there listening, only a few atoms per second would impact our eardrum, and we wouldn't be able to hear the sound because our ears aren't sensitive enough.
In her estimate the rate needed to be roughly 1 × 1026 oxygen atoms per second or 1.2 × 108 cm−2 s−108
The measured TOF is 47±8 CO2 molecules per deposited atom per second at 350 K and the observed mechanistic details can be explained by different active centers on the clusters and by the competitive adsorption of the two reactant molecules.
The turnover frequency (TOF) of NB on each catalyst is defined as the number of moles of NB converted per one surface Ni atom per second [12].
The turnover frequency, that is, the number of catalytic cycle per active site (palladium atom and its surrounding silver or copper atoms) and per second, seems to be independent of surface composition of alloy particles and 1,2-dichloroethane hydrodechlorination is insensitive to the atom's nature (silver or copper).
One Curie is equivalent to 37 billion radioactive atoms disintegrating per second.
For instance, in the average building, typically you'll find radon levels of 1 picoCuries per liter of air (this is equivalent to 0.037 radioactive atoms disintegrating per second in that liter of air).
However, the amount of radioactive atoms disintegrating per second as a result of the presence of radon in air is only a very small fraction of a Curie amount.
In 1985, Dr. Chu and his colleagues at Bell Labs cooled a cloud of atoms to 240 millionths of a degree above absolute zero with what he called "optical molasses". They did it by bathing the atoms in laser beams fired together from all directions, which created a kind of drag that slowed the atoms to inches per second, corresponding to the low temperature.
