How many p-orbitals are occupied in a K atom?
Since you're dealing with a neutral atom, the number of electrons
As you can see, the 2p and 3p sublevels each hold six electrons, which means that they are completely occupied. Since every p sublevel has a total of three p-orbitals -
A faster way to figuring out how many p-orbitals are occupied in a
So, all you have to do is read the periodic table from left to right across each period - much like you would a sentence - until you get to potassium.
If you do this, you'll notice that you've passed two p sublevels: the one that starts at
