Reaction of roentgenium with air

As only a few atoms of roentgenium have ever been made, its reactivity with air is unknown. One would predict its behaviour to be similar to that of gold (immediately above roentgenium in the periodic table) and silver (two places above).

Reaction of roentgenium with water

As only a few atoms of roentgenium have ever been made, its reactivity with water is unknown. One would predict its behaviour to be similar to that of gold (immediately above roentgenium in the periodic table) and silver (two places above).

Reaction of roentgenium with the halogens

As only a few atoms of roentgenium have ever been made, its reactivity with the halogens is unknown. One would predict its behaviour to be similar to that of gold (immediately above roentgenium in the periodic table) and silver (two places above).

Reaction of roentgenium with acids

As only a few atoms of roentgenium have ever been made, its reactivity with acid is unknown. One would predict its behaviour to be similar to that of gold (immediately above roentgenium in the periodic table) and silver (two places above).

Reaction of roentgenium with bases

As only a few atoms of roentgenium have ever been made, its reactivity with bases is unknown. One would predict its behaviour to be similar to that of gold (immediately above roentgenium in the periodic table) and silver (two places above).
