Calculate the number of valence electrons in Einsteinium using its electron configuration step by step.
Determine the number of valence electrons in Einsteinium (Es, Element 99)
The abbreviated (condensed) ground electronic configuration for Einsteinium is:
Calculate Electronic Configuration for Einsteinium
Electrons in all the atomic orbitals are the outermost electrons:
Extract the principle quantum number, n, and number of electrons from the electron configuration:
Electron Configuration | n | Orbital | Number of Electrons |
---|
The outermost electrons with the largest principal quantum number (in this case, n = 0) are valence electrons.
Einsteinium (Es) has 0 valence electron(s).
