(a) Explanation Given info: The Pickering series is produced when electrons jump from a higher level to the n = 4 level of He + . The spectral lines are produced by singly ionized helium The expression for spectral lines in the Pickering series is, 1 λ = C ( 1 16 − 1 n 2 ) (1) Here, n is 5 , 6 , 7... . C is constant. Expression to calculate energy of a photon emitted when an electron jumps from higher energy state to lower energy state is, Δ E = E i − E f (2) Here, E i is the energy of an electron in lower energy state. E f is the energy of an electron in higher energy state. Expression to calculate the energy in the state n is, E n = − 13.6 Z 2 n 2 (3) Here, Z is the atomic number. Substitute 1 for Z in hydrogen and n i for n in equation (3) to get E i . E i = − 13.6 ( 1 ) 2 n i 2 Thus, the energy of an electron in lower energy state is − 13.6 ( 1 ) 2 n i 2 . Substitute 1 for Z in hydrogen and n f for n in equation (3) to get E f . E f = − 13.6 ( 1 ) 2 n f 2 Thus, the energy of an electron in higher energy state is − 13.6 ( 1 ) 2 n f 2 . Substitute − 13.6 ( 1 ) 2 n f 2 for E f and − 13.6 ( 1 ) 2 n i 2 for E i in equation (2) to get Δ E for hydrogen atom. ( Δ E ) hydogen = ( − 13.6 ( 1 ) 2 n i 2 ) − ( − 13.6 ( 1 ) 2 n f 2 ) = 13.6 ( 1 n f 2 − 1 n i 2 ) eV Thus, energy of a photon emitted for hydrogen atom is 13.6 ( 1 n f 2 − 1 n i 2 ) eV . The expression to calculate the energy in the state n for singly ionized helium atom is equation (3) Substitute 2 as Z in singly ionized helium atom and n i for n in equation (3) to get E i . E i = − 13.6 ( 2 ) 2 n i 2 Substitute 2 as Z in singly ionized helium atom and n f for n in equation (3) to get E f . E f = − 13.6 ( 2 ) 2 n f 2 Substitute − 13.6 ( 1 ) 2 n f 2 for E f and − 13 (b) To determine The numerical value of C . (c) To determine To verify: Pickering lines for n = 6 correspond to Balmer lines in hydrogen.

Quantum mechanics and hydrogen atom

Consider an electron of mass m moves with the velocity v in a hydrogen atom. If an electron is at a distance r from the proton, then the potential energy function of the electron can be written as follows:

Isotopes of Hydrogen Atoms

To understand isotopes, it's easiest to learn the simplest system. Hydrogen, the most basic nucleus, has received a great deal of attention. Several of the results seen in more complex nuclei can be seen in hydrogen isotopes. An isotope is a nucleus of t…
