Question

Hydrogen at has only 1 electron . How come hydrogen spectrum has number of bright light ?​

Answer 1

Answer:

Explanation:

hydrogen has  1 electrons but it has infinite number of shells or orbits [ note that any atom has infinite shells] So, when this single electron of hydrogen gains some energy in the form of wave, it jumps to higher orbits depending on the frequency of the wave gained. For example, if it gains a photon of 10.2ev, it goes from 1st to 2nd orbit. And, if it gains a photon of 12.09 eV, it goes from 1st shell to 3rd shell. While back to the 1st shell again, from 2nd and 3rd shell in these two cases, it emits energy [ because it comes to lower energy level from higher energy level], and this line comes under lyman series. Now, if the electron gains 1.89 eV energy, it goes to 3rd shell from 2nd shell, while coming back to its 2nd shell, it will emit energy. This line comes under balmer series.

hence, spectrum does not depend on number of electrons but upon the energy gained and emitted by the electron.
