which are sufficientlyenergeticto cause ionization of inner electrons of the atoms. Because of this unstable atomic configuration, this vacancy of an inner electron is filled by an electron from an outer orbital, which emitted the difference of energy between the two orbitals as a ‘secondary’ (...
Sign in to download full-size image 301. Furan derivatives have been prepared by the intramolecular cyclization of β,γ-unsaturated enolates. The reaction proceeds through a nucleophilic attack at the unsaturated bond by the enolate ion oxygen (Scheme 79) 〈77H(8)417〉. This reaction is fac...
The ground-state electron configuration of the potassium ion K+ is {eq}1s^2, 2s^2, 2p^6, 3s^2, 3p^6 {/eq}. This gives us an identical electron... See full answer below.Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a ...
Full size image slo-1; slo-2 double mutants are faster to change preference Since a gf mutation in slo-2 decelerated the transition of temperature preference, we examined whether loss of slo-2 accelerated the transition. We revealed that the preference transition was not accelerated in slo-2(...
