About Nihonium
Nihonium has the symbol Nh and atomic number 113, which means every nihonium atom has 113 protons in its nucleus and, in a neutral atom, 113 electrons. At room temperature it is unknown (too few atoms have been made).
Only a few atoms of this element have ever been made, in particle accelerators, so most of its properties are predicted rather than measured.
