2 slow moving hydrogen atoms - distance to start interaction

In summary, the distance at which 2 hydrogen atoms begin to attract each other is not specified as the electromagnetic force works at all distances. However, the attraction drops off rapidly at a rate of 1/r^6, where r is the distance. The formation of a molecule between the two atoms depends on the ability to measure small accelerations. Online references for the 1/r^6 calculation can be found.

At what distance do 2 hydrogen atoms (not ions) begin to attract each other?

No, this is not a homework question. I am 58.

Well, in theory there's no distance where that begins or ends; they attract at all distances since the electromagnetic force works at all distances.
But the attraction drops off rapidly; in proportion to 1/r^6, where r is the distance.

Guess I should have specified at what distance would acceleration be observed?
I'm assuming the 2 hydrogen atoms will form a molecule at the end of the cycle.

That depends on how small an acceleration you can measure.

Not sure. How about 1 m/s^2

Do you know any online references for the 1/r^6 calculation? Thanks
 

1. What is the distance between two slow-moving hydrogen atoms for them to start interacting?

The distance between two slow-moving hydrogen atoms for them to start interacting is typically around 0.74 nanometers (nm).

2. How does the speed of the hydrogen atoms affect their interaction distance?

The speed of the hydrogen atoms does not significantly affect their interaction distance, as long as they are moving slow enough to be considered stationary. However, if they are moving too quickly, their interaction distance may decrease due to the repulsion of their electron clouds.

3. Can the interaction distance between two slow-moving hydrogen atoms be changed?

The interaction distance between two slow-moving hydrogen atoms is determined by their electron clouds and cannot be changed. However, external factors such as temperature and pressure can affect the distance at which the atoms are stationary and thus, their interaction distance.

4. What is the significance of the distance between two slow-moving hydrogen atoms?

The distance between two slow-moving hydrogen atoms is significant because it determines when they will start interacting and forming chemical bonds. This distance is also important in understanding the behavior and properties of molecules and materials composed of hydrogen atoms.

5. How is the interaction distance between two slow-moving hydrogen atoms measured?

The interaction distance between two slow-moving hydrogen atoms can be measured using various techniques such as X-ray crystallography, spectroscopy, and electron microscopy. These methods allow scientists to observe the atoms and their electron clouds, providing insights into their interaction distance and behavior.
