WebThe lowest excitated state of helium is represented by the electron configuration 1s 2s. The 1 s 2 p configuration has higher energy, even though the 2 s and 2 p orbitals in hydrogen are degenerate, because the 2 s penetrates closer to the nucleus, where the potential … WebFor this process to occur there must be an electron in the lower-energy level to start with. There must also be space in the higher level for the electron to move into. The gaps (dark lines) in an absorption spectrum are formed because light of the specific energy (or wavelength, if you prefer) in the dark lines is absorbed by the atoms in a gas.

WebEach electron shell has a different energy level, with those shells closest to the nucleus being lower in energy than those farther from the nucleus. ... neon has a complete outer 2n shell containing eight electrons. These electron configurations make helium and neon very stable. Although argon does not technically have a full outer shell, ...
