Osmium
The most common isotope of osmium is 192 Os. All osmium isotopes contain 76 electrons.
Reference to a periodic table or similar reference source shows that there is such an element, and it has the name "osmium".
mercury has 121 nutrons because the periodic table
Osmium is a metal
mass number= protons+nutrons
Sum of protons and nutrons
