Created by StemPy LabAn atomic orbital has exactly two radial nodes (spheres on which the wave function is zero) and exactly one angular node (a plane or cone through the nucleus on which it is zero). Which of the following orbitals is it?

← In a sample of hydrogen atoms, every electron is in the orbit n = 6. The electrons fall back to the ground state by every possible path, one jump at a time or several. Light of wavelength longer than 750 nm is infrared. How many different spectral lines in the infrared can the sample give out? Take RH = 109 677 cm⁻¹.Count the unpaired electrons of each atom and ion below in its ground state. In which pair are the two counts equal? Chromium has atomic number 24, manganese 25, iron 26, cobalt 27 and copper 29. Think about the unusual configurations of chromium and copper, and about which electrons leave first when a positive ion forms. →
