Hydrogen is the simplest element with its atom having only one electron. Hence, the atomic spectrum of hydrogen has played a significant role in the development of atomic structure. In the emission spectrum of hydrogen, when an electric discharge is passed through hydrogen gas, the molecules of hydrogen break into atoms. The hydrogen atoms get energized and go into an excited state. The excited atoms then return to the ground state by emitting light. Hydrogen atoms emit bluish light. On passing this light through a prism, a discontinuous line spectrum consisting of several sharp lines is obtained. This is the line spectrum of hydrogen.
Bohr's all things are applicable only to those atoms having only one electron in the atom.Hence, we have hydrogen as the atom having only one electron (that also sometimes).
Hope it is useful..!
thank you! Is this helpful for preparing s.a-1 for state syllabus 10th?
I dont know.I have just learnt all this for studying for my olympiads.You can check in your textbook and edit the answer according to your needs.
whats da syallbus for sa 1 state 10 clz admin
Because BOHR was the first person to explain the spectrum and hydrogen atom was the simplest atom so he first worked out with that.
