![]() You only need to change the number in the final orbital - the rest is the same since the orbitals before the final one are completely full. Notice that the number of electrons adds up to 17: 2 + 2 + 6 + 2 + 5 = 17.For example, if we want to make the orbital diagram for chlorine (Cl), element 17, which has 17 electrons, we would do it like this: Now that you have this, all you need to do to find another atom's electron configuration is just fill in this pattern from the beginning until you run out of electrons.It has the most electrons of any element, so its electron configuration demonstrates all of the possibilities you could encounter in other elements:ġs 22s 22p 63s 23p 64s 23d 104p 65s 24d 105p 66s 24f 145d 106p 67s 25f 146d 107p 6 Examine complete electron configuration for oganesson (Og), element 118, which is the last element on the periodic table.If you have to find it yourself, see below: X Research source Once you know an element's electron configuration, finding its number of valence electrons is quite simple (except, of course, for the transition metals.) If you're given the configuration from the get-go, you can skip to the next step. Their electron capacities are as follows:įind the electron configuration for the element you are examining. Keep in mind that each subshell has a certain electron capacity.That's 11 electrons total - sodium is element number 11, so this makes sense. So, for our example, we would say that sodium has 2 electrons in the 1s orbital plus 2 electrons in the 2s orbital plus 6 electrons in the 2p orbital plus 1 electron in the 3s orbital.The (number)(letter) chunk is the name of the electron orbital and the (raised number) is the number of electrons in that orbital - that's it! (number)(letter) (raised number)(number)(letter) (raised number). Notice that this electron configuration is just a repeating string that goes like this:. ![]()
