Azufre: (Z=16) grupo 16 Sodio: (Z=11) grupo 1 Calcio: (Z=20) grupo 2 Fluor: (Z=9) grupo 17 a)- Realiza su configuración electrónica. b)- Indica cuál será su capa de valencia y cuántos electrones contiene. c)- Explica razonadamente cómo consigue cada elemento la configuración electrónica más estable.

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.
