115 Mc 289

Moscovium

unknown, probably post-transition metal · period 7 · group 15 (pnictogens) · p-block

Moscovium is a synthetic chemical element with the symbol Mc and atomic number 115. It was first synthesized in 2003 by a joint team of Russian and American scientists at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia.

What the numbers say

At standard temperature and pressure Moscovium is a solid, sitting in period 7, group 15 of the p-block.

Its melting point of 670 K (397 °C) is the 76th highest of the 110 elements with a measured value — mid-range among the elements.

First identified in 2004.
