Question

Calculate the speed of an electron in the ground state of he +ion .What fraction of speed of light is ths

Answer 1

For example, with just over 220,000 eV (which stands for a convenient unit of energy called the "electron-volt"), you can get the electron up to 90% of the speed of light. But to get it to 99.9% (just another 9.9 percentage points), you need a total of over 11 million eV!

Answer 2

Answer:

It is the speed on the state of ion by the dravyon of the speed of light.#
