Respuesta :
Osmium exists the 76th element in the periodic table and its symbol is ‘Os’. The electron configuration of osmium is [Xe] 4f14 5d6 6s2.
How to write an electronic configuration?
- Find the element's atomic number using the periodic table. Before expressing the electron configuration, list the energy level and kind of orbital first, then the number of electrons in the orbital as a superscript.
- The simplest approach to express the electronic configuration of any element is to use the diagonal rule of the Aufbau principle for electron filling order in the various subshells. The three rules that must be followed when expressing the electron configuration in the orbital box diagram are the Aufbau rule, the Pauli-exclusion rule, and Hund's Rule.
- Electron configurations make it simple to record the positions of every electron in an atom. It is common knowledge that in the atomic nucleus, negatively charged electrons are drawn to positively charged protons.
