ROENTGENIUM

Roentgenium is expected to have properties that are similar to those of the elements in Group 11 of the periodic table, which includes copper, silver, and gold. Like these metals, Roentgenium is predicted to have a metallic luster, be a good conductor of electricity, and have a relatively high melting and boiling point. However, due to its high reactivity, these predictions have yet to be fully confirmed... Roentgenium is a highly reactive element and is expected to behave similarly to the other Group 11 elements. It is expected to have a +1 oxidation state, which is common for Group 11 metals. However, due to its short half-life, it is difficult to study the chemical properties of Roentgenium in detail... Roentgenium is the heaviest known element in group 11, which also includes copper, silver, and gold.
