The camouflaged atom behaves chemically like hydrogen, but has four times the mass of normal hydrogen, allowing predictions for how atomic mass affects reaction rates to be put … Close Advertisement ...

Using a mass spectrometer, physicists have determined the mass of a hydrogen atom to be 1.660538921(73) × 10-27 kilograms, where the parenthetical digits are not known with complete certainty.

The heavier the atom, the more protons (and neutrons) it contains.Hydrogen, which is the lightest element, has a nucleus made from a single proton. The heaviest element in the Periodic Table ...

Vrakking says that the ultimate goal of the research was to study and visualize the hydrogen atom. Future experiments may look at how the atom would react within a magnetic field, study time-resolved ...

If you convert the entirety of a hydrogen atom into energy, you get 1.5 x 10-10 Joules, That looks like a very small number, and it is; but gamma radiation is usually bad for you, right? Let’s ...
