Ununseptium is a temporary name established after IUPAC rules for naming new discovered artificial chemical elements up to a sure validation of the discovery. The name is from Latin:
un=1, un=1 septium=the seventh---------117
Ununseptium is expected to be a solid at room temperature. It is a synthetic element that is highly unstable and has a very short half-life, so it has not been observed in its solid state at room temperature.
Unundeptium has 117 protons and electrons; the number of neutrons is 176 or 177, depending on the isotope.
The last element to be discovered was tennessine, with the atomic number 117. It was officially recognized by the International Union of Pure and Applied Chemistry (IUPAC) in 2016. Tennessine is a synthetic element that is highly unstable and only exists for a very short period of time.
The metalloid that would have chemical properties similar to bromine is arsenic. Arsenic exhibits similar covalent bonding characteristics as bromine and can also form compounds with similar reactivity.
It is supposed that ununseptium is a halogen (non metal).
The symbol for ununseptium is Uus.
