WebAn ion, atom, or a molecule containing an unpaired valence electron is called a free radical. These species disobey the octet rule. However, they are very unstable and tend to spontaneously dimerize. Since the first shell can only accommodate two electrons, elements such as lithium, helium, and hydrogen obey the duet rule instead of the octet rule. Web10 apr. 2024 · These include: (i) The intrinsic electron transfer rates within the different catalysts; (ii) The concentrations of free radical spin defects in the different materials, noting that PCS-1 does not have the highest spin concentration (Table S1); (iii) The relative accessibilities of the active catalytic sites in the 2D PCS-1 compared with the 3D …
