Give the maximum number of electrons in an atom that can have these quantum numbers.n
(a) = 2, l = 2
The elements Cu, O, La, Y, Ba, Tl, and Bi are all found in high-temperature ceramic superconductors. Write the expected electron configuration for these atoms. (Put answer in noble gas notation using the format [Ar] 4s2 3d10 4p3 for [Ar] 4s2 3d10 4p3.)
Tl:
For TI, [Xe] 4f14 5d10 6s2 6p1 and [Xe] 5d10 4f14 6s2 6p1 are both incorrect. [Xe] is the correct noble gas, but the numbers are incorrect.
Bi:
For Bi, [Xe] 4f14 5d10 6s2 6p3 and [Xe] 5d10 4f14 6s2 6p3 are both incorrect. [Xe] is the correct noble gas, but the numbers are incorrect.
Explain a wavelength of 925.4 nm has been detected from the emission of a hydrogen gas tube while under excitation from a high voltage source in a lab. This was caused by an electron dropping from a higher voltage source.
