osmium atomic mass

In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all … The electron configuration of osmium is [Xe] 4f145d66s2. Osmium has an atomic mass of 190.23 u. The chemical element Osmium is classed as hard, brittle, bluish-white transition metal.Its atomic number is 76 and represented by the symbol Os. There are six stable isotopes of osmium, osmium-184, osmium-187, osmium-188, osmium-189, osmium-190 and osmium-192. Density is determined by mass over volume. Osmium has a bluish-silvery lustre. The mass of an atom is determined by how many heavy particles (protons and neutrons) are in the nucleus. Osmium is a hard, brittle, bluish-white transition metal in the platinum group that is found as a … It is very densest metal, even little more than iridium (22.56 g/cm 3).. Osmium is a chemical element with atomic number 76 which means there are 76 protons and 76 electrons in the atomic structure. Osmium (76 Os) has seven naturally occurring isotopes, six of which are stable: 184 Os, 187 Os, 188 Os, 189 Os, 190 Os, and (most abundant) 192 Os. At this time, osmium had the largest uncertainty among all standard atomic weights, equalled with lead (for which, however, the atomic weight is affected by natural variability, not applicable to osmium). Atomic mass. Atomic number. The most abundant stable isotope is osmium-192. Check my Elements Comprehensive List. Video Are you having trouble understanding the basics of atomic elements?
