I've been wondering about the velocity of hydrogen electrons. I've read that 242,000 m/s was the correct velocity, however, I thought electrons would travel at c. How does one calculate this number?

Thanks in advance.

One can measure/calculate the mean momentum & kinetic energy of the atomic electron, then it is trival to obtain its velocity.

mv^2=27 eV, so [tex]v/c=\sqrt{27/500,000}[/tex]

Can you explain that equation, if you get a chance? Why does mv^2=27ev

Thanks.

Thanks.

The velocity of atomic (hydrogen) electrons refers to the speed at which the electrons orbit around the nucleus of a hydrogen atom. This velocity can vary depending on the energy level of the electron and its distance from the nucleus.

The velocity of atomic (hydrogen) electrons can be determined using the equation v = √(2E/m), where v is the velocity, E is the energy level of the electron, and m is the mass of the electron. This equation is based on the principles of quantum mechanics.

The velocity of atomic (hydrogen) electrons is significant because it helps us understand the behavior and properties of atoms. It also plays a crucial role in chemical reactions and the formation of molecules.

Yes, the velocity of atomic (hydrogen) electrons can be changed by altering the energy level of the electron. This can be done through various means, such as applying an external electric field or exciting the electron with a photon.

The velocity of atomic (hydrogen) electrons is closely related to the concept of orbital shells. The different energy levels of the electrons correspond to different orbital shells, and the velocity of the electrons is determined by the size and shape of these shells. As the energy level increases, the orbital shell becomes larger and the velocity of the electron also increases.
