Calculate the wavelength of the lowest energy transition in the Brackett series of the electronic spectrum of the Li+ ion. The Rydberg constant for He is RLi = 109729 cm–1.
A line in the Paschen series of the emission spectrum of atomic hydrogen is observed at a wavenumber of 7800 cm–1. Deduce the upper state principal quantum number for this transition.
Calculate, from the fundamental constants, the value of the Rydberg constant for a deuterium atom.
What is the degeneracy of the energy level with n = 6 in a hydrogenic atom or ion?
How many nodes does a 4d orbital possess?
The change in energy when an electron is transferred between a neutral potassium and a neutral bromine atom to produce a positively charged potassium cation and negatively charged bromine anion
K(g) + Br(g) ® K+(g) + Br–(g) is 93.6 kJ mol–1. The ionization energy of a potassium atom is 4.34 eV. Calculate the electron affinity of a neutral bromine atom.
To which orbitals may an electron in a 2p orbital in a hydrogenic atom make allowed spectroscopic transitions?
What terms can arise from the configuration 2p13p1?
Predict the levels that may arise from a 2P term of an excited potassium atom.
Atomic carbon, C, has a ground electronic configuration that gives rise to the levels 3P2,1,0, 1D2 and 1S0. Use Hund's rule to predict which of these levels is lowest in energy.
