Which of these trends increase as you go from top to bottom on the Periodic Table? Select all that apply. A. electron affinity
B. atomic radi
C. electronegativity
D. ionization energy
E. activity series of metals

b. atomic radius

as it goes increases when it goes down the periodic table, it decreases when going left to right. all the others decrease while going down the table.

if it helps you to remember, everything here besides atomic radius has an e in it. and if you make a connection with it to electrons, they are negative, which means they would decrease going down the table. so e=decrease while going down

thats what helped me remember it, so i hope this technique could help you too.

i believe it is-
