So, for example, if we wanted to know the electron configuration for sodium (atomic number 11), we start at the top left and follow that arrow to 1s2 (we can only add two electrons to an "s" orbital).(See orbital list in the lower right of the graphic).

Question:I understand how to write the electron configurations of elements that only use the s orbital and p orbital, but when there are more than 3 energy levels with more than 8 electrons, you begin to use d orbitals and f orbitals.How do I do that? What is an easy way to calculate the electron configurations of elements in the d- and f- blocks? And how do I calculate the electron ...

For example, 1s^2 is the proper notation for helium, with the numeral "1" representing the first orbital level, "s" representing the type of orbital and the exponent "2" showing that there are two electrons in that orbital. In addition, 1s^1 represents hydrogen because the exponent shows that orbital holds only one electron.

Electron Configurations. This program determines the information shown below for either an atom or an ion. Conventional notation is used, i.e. - the first letter of an element is capitalized and the second is a small letter. When entering the charge for an ion, it can be entered as +2 or 2+, i.e. Ca 2+ or Ca +2.
