Answer: (a) The hydrogen emission spectrum comprises radiation of discrete frequencies. Q4. Atomic hydrogen displays. Answer: (a) Atomic hydrogen displays emission spectrum. Q5. WebA Danish physicist, Niels Bohr (1885 – 1962), used the work of Planck and Einstein to apply a model to explain the stability and the line spectrum of a hydrogen atom. Bohr’s postulates follow: 1. Energy Level Postulate: The electron can only have specific energy values in the hydrogen atom.

In the Bohr Shell model, electrons can exist only at certain energy levels (also called shells), not at any energy levels between them. Shells in this energy diagram go from 1 to 6. An increase in

WebThe electron’s speed is largest in the first Bohr orbit, for n = 1, which is the orbit closest to the nucleus. The radius of the first Bohr orbit is called the Bohr radius of hydrogen, denoted as a0. Its value is obtained by setting n = 1 in Equation 6.38: a0 = 4πε0 ℏ2 mee2 = 5.29 × 10−11m = 0.529Å. 6.39. WebThis is an extremely useful equation, so usually you see this called the Balmer-Rydberg equation. We've derived this equation using the assumptions of the Bohr model, and this equation is extremely useful because it explains the entire emission spectrum of hydrogen. This is again, this is why we were exploring the Bohr model in the first place.

WebFor the hydrogen atom, ni = 2 corresponds to the Balmer series. There are other series in the hydrogen atom that have been measured. The Lyman series is a set of ultraviolet lines that fit the relationship with ni = 1. A series in the infrared region of the spectrum is the Paschen series that corresponds to ni = 3.
