Witryna7 kwi 2024 · These properties of lithium are similar to magnesium, which is diagonally placed in the next series. Both elements show the following same properties: The lithium and magnesium ions have comparable melting and boiling points. ... Both have a reducing character because of which they exhibit similar properties. Beryllium and … WitrynaLithium, beryllium, and magnesium are the only members exhibiting a covalent chemistry. All the elements of this group have nuclei with quadrupole moments, and for this reason high-resolution NMR spectra of most of these nuclei exhibit severe line broadening. Notable exceptions are 9 Be, 133 Cs, and the lithium isotopes 6 Li and 7 Li. fsm world
