Lanthanum - Electron Affinity - Electronegativity
Webters along with their adiabatic and vertical ionization energies were computed from the density functional theory using B3LYP and PW91GGA exchange correlation functionals. Favorable agreement between the computed and experimental ionization energies allows assignments of the ground state structures for these clusters. For La 3O 4, a C WebThe key properties of lanthanum are: It is an active metal. It forms compounds with nitrogen, carbon, boron, selenium, phosphorus, silicon, sulfur and with the halogens. It is a soft malleable silvery metal that can be cut with a knife It reacts very quickly with hot water and most of the acids. It reacts slowly with cold water photo cd album
