Roentgenium is a synthetically produced element classified as a transition metal. It is also considered one of the noble metals, meaning metals that are resistant to reacting with most other elements.Answer and Explanation: The hardness of roentgenium is unknown because researchers have only produced ...
3.18. An increase in Cdi atom concentration near the surface layer leads to an increase of the materials radiation hardness due to two facts: that Cd atomic weight is larger compared to other atoms – Zn and Te, and ‘healing’ of the crystal lattice by Cdi atoms – recombination Vcd and...
