WebTraductions en contexte de "density multiple" en anglais-français avec Reverso Context : As a result, a single level layer of high density multiple conductive elements may be fabricated. WebDensity. The high density of d-block elements is due to their short atomic size and strong metallic bonds. The density trend in the transition series is inverse to the atomic radii, i.e., it grows initially, stabilises, and finally drops. When cooled to room temperature, osmium density is 22.57gcm –3.
