Hi! I only memorized the atomic number (using the major system) and the element’s symbol with some clues embedded in my “story” to help me, such as a Ferris wheel having iron seats (Fe being the symbol for iron).
I have shared my elements memory palace/story in another thread on art of memory. You may be able to use at least some of it in your own memorization. If you’re interested, it’s here:

I also memorized the groups of elements by placing them in a memory palace with some basic properties represented. For instance, group 1 are the Alkali metals. My memory palace is my brother’s house. I’m arrive at his house with ALCOHOL. Everything is exploding, because elements in this group are unstable and highly reactive. The first thing I see in the driveway is a pile of LITHIUM batteries, and on and on.
I’m no scientist, but it really made me appreciate the periodic table!!
