Answer to Question #229428 in General Chemistry for Aniekan

Question

A photon of 498nm was emitted from a silicon atom.calculate the energy of the atomic levels of silicon and show that the atomic levels are quantized

Answer 1

Silicon belongs to the elements of the p-family. The electronic formula of silicon is 1s22s22p63s23p2. There are four electrons at the external energy level – a pair of electrons at the 3s level and two unpaired electrons at the 3p level. Due to the distribution of electrons, the atom exhibits an oxidation state of 2.
