The series present in hydrogen spectrum are:- Write the names of five spectral series present in line spectrum of Hydrogen atom. Bohr’s Model of Hydrogen Atom: Drawbacks of Rutherford’s atomic model lead to the Bohr’s Model where he came up with 3 postulates: ppt on hydrogen for class XI th chemistry 1. Every atom is a sphere of radius of the order of 10-10 m, in which entire mass is uniformly distributed and negative charged electrons revolve around the nucleus. Qs. It is important to note that, such a spectrum consists of bright lines on a dark background. That energy must be exactly the same as the energy gap between the 3-level and the 2-level in the hydrogen atom. This is an emission line spectrum. 1. Line Spectrum of Hydrogen. French chemist Antoine Lavoisier named hydrogen from the Greek words for “water former.” Hydrogen has the smallest atoms of any element. Note: This photograph is by courtesy of Dr Rod Nave of the Department of Physics and Astronomy at Georgia State University, Atlanta.The photograph comes from notes about the hydrogen spectrum in his HyperPhysics pages on the University site. That energy must be exactly the same as the energy gap between the 3-level and the 2-level in the hydrogen atom. line with 486.1 nm in the blue green called Hß, third line 434.1 nm in the violet is called Hr. This is the origin of the red line in the hydrogen spectrum. The hydrogen atom is said to be stable when the electron present in it revolves around the nucleus in the first orbit having the principal quantum number n = 1.

Four of the Balmer lines are in the technically "visible" part of the spectrum, with wavelengths longer than 400 nm and shorter than 700 nm. There are emission lines from hydrogen that fall outside of these series, such as the 21 cm line.These emission lines correspond to much rarer atomic events such as hyperfine transitions. Parts of the Balmer series can be seen in the solar spectrum. Solve free mcqs on bohr's theory and hydrogen line spectra class 11 chemistry ch 2, helpful for CBSE, NEET / AIPMT & JEE preparation.
