Chemical reactions of the elements

Reaction of ununseptium with air

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

Reaction of ununseptium with water

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

Reaction of ununseptium with the halogens

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

Reaction of ununseptium with acids

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

Reaction of ununseptium with bases

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