What are the periodic table trends for acidity, basicity, and nucleophilicity?
BEANS. Look at a periodic table and write a "B" on the top left, "E" on the top right, "A" on the bottom right, and an "N" and "S" on the bottom left. All those increase in a direction towards that letter.
B=Basicity
E=Electronegativity, ionization Energy, and Electron affinity
A=Acidity
N=Nucleophilicity
S=Shielding
In regards to the post above, the nucleophilicity trend is the same as the basicity trend going across a row only. Within the same group, the trend is the opposite. In other words, both "N" and "B" increase from right to left, but "B" increases bottom to top and "N" increases top to bottom. Just remember BEANS. You can also think of it as BEARS. R=atomic Radius. Just replace the "N" with the "R." Hope this helps

Awesome. Definitely a good one to use.
Also, we can put the leaving group (LG) ability in the acidity corner, right?
Increasing acidity = same trend as better leaving group
Wow, this is really helpful. Thanks!
