Bohrium

Bohrium is atom number 107 — every Bohrium atom has exactly 107 protons in its center, and that number is what makes it Bohrium and nothing else. Its symbol is Bh. At room temperature it is a solid.

Bohrium is a chemical element with symbol Bh and atomic number 107. It is named after Danish physicist Niels Bohr. It is a synthetic element (an element that can be created in a laboratory but is not found in nature) and radioactive; the most stable known isotope, 270Bh, has a half-life of approximately 61 seconds.
