Question

Using the periodic table to locate each element, write the electron configuration of(a) Ru;

Answer 1

Ruthenium is a chemical element with the symbol Ru and atomic number 44. The electron configuration of Ru is $5s14d^{7}$.

How to write an electronic configuration?

• Find the supplied element's atomic number on the periodic table and identify it.
• The energy level and kind of orbital should be listed first, followed by the number of electrons in the orbital in superscript.
• The Aufbau principle's diagonal rule for electron filling order in the various subshells is the simplest way to express the electronic configuration of any element.
• The Aufbau rule, the Pauli-exclusion rule, and Hund's Rule are the three rules that must be followed when expressing the electron configuration in the orbital box diagram.
