Match each set of energy sublevels to the principal energy level that contains them.

In the world of quantum mechanics, each principal energy level (n) contains different types of sublevels, which are like cozy homes for electrons! For instance, the first principal energy level (n=1) has only the 1s sublevel, perfect for its simplicity. As we climb the energy ladder to n=2, we find both the 2s and 2p sublevels, making it a bit more social. Moving up to n=3, we’ve got 3s, 3p, and 3d, adding even more rooms for our electrons to mingle!

As you dig into these energy levels, bear in mind that higher principal levels can hold more sublevels and electrons. By the time you hit n=4, you’ll discover 4s, 4p, 4d, and 4f sublevels, which is like entering an extravagant multi-story mansion! Just remember, the complex interplay between these levels and sublevels is key to understanding the periodic table and the behavior of elements. It’s all about finding the right “room” for our favorite electrons!
