-**Electron configuration** is given as a string, with each orbital separated by a space.  **Electron shells** are given as an array, the first item is the number of electrons in the first shell, the 2nd item is the number of electrons in the second shell, and so on.
+**Electron configuration** is given as a string, with each orbital separated by a space.  **Electron configuration semantic** is given as a string, this is the short-hand version of the electron configuration. Elements with a semantic electron configuration marked with a "*" mean that the electron configuration has not yet been confirmed. **Electron shells** are given as an array, the first item is the number of electrons in the first shell, the 2nd item is the number of electrons in the second shell, and so on.
 
 Both **ionization energy** and **first electron affinities** are given as the energy required to *detach* an electron from the anion.  Ionization energies are given as an array for successive ionization energy.
