Y'all know of any mnemonics for the periodic table trends? to help remember the trends across the table? thank youuuu

Hi!

This isn't a mnemonic (wish I had one), but it is very helpful. There is a lot to remember, so just focus on electronegativity and ionization energy. Those are the big two that affect the rest, so knowing those will give you most of the information you need. Look at this video, too (super helpful in my opinion!):

I don't know any mnemonics, but I can try to help.

If we're just talking about electron affinity, ionization energy, and atomic radius, you can just remember one: that atomic radius increases as you go to the left and downwards. The other 2 trends are just the opposite (IE and electron affinity increase as you go up and right).

Put simply, there are only two types of trends we observe.
Atomic radius which increases down a group and decreases across a period from left to right.
The remaining three that is electronegativity, electron affinity, and ionization energy decrease down a group, and increase across a period from left to right.
If you learn one of them, the other is just the opposite.
