The MCAT (Medical College Admission Test) is offered by the AAMC and is a required exam for admission to medical schools in the USA and Canada. lol the greediest atoms once again are to the top right.Welcome to the BEST place for MCAT prep and practice materials. Ionization energy- increases up to the right b/c its wayyy harder to take an ION from a greedy electronegative atomĪtomic radii- like I said the groups that are fatter are wider!Įlectronegativity- ill let you guess by now. Sheilding- increases downward because the atoms are fatter “think more fluff” more electronegative groups are greedy for protons More electronegative=more greedy=like to hold on=weak acid=stronger base=smaller radii=less shielding.Īcidity- increases downward because an acid likes to LOSE its protons we know fatter groups (more polar bonds) make great acids hence HCL (acid in ur stomach) is way stronger than HF. Just by knowing the P table u can answer more questions than you think. If you got that down solid it will tell you EVERYTHING u need to know. across a period atoms are getting smaller and more greedy for electrons. Its telling you something.ĭown a group atoms are getting fatter and dont care about losing electrons. understanding helps you not freak out during the test under high stress. Hey! Mnemonics are great dont get me wrong but. Would totally encourage you all to make maps your own!! Easier than actually understanding the concepts behind the patterns □ Ionization Energy: Ionization = the start of the nation (a slant rhyme, but it works for me), points up rightĮlectron affinity: An affinity for my city (I'm from Boston), up and right. Shielding: The wall shields us from Mexico, points straight down It's dumb, but it works!), points down and right I imagine the periodic table as a map of the US, and make mnemonics based on what region the arrow is pointing to (arrow points in increasing direction)Īcidity: I think about throwing acid in someone's face, which is some kind of Florida Man headline (but lol it really came from Jane the Virgin, Petra's mom got acid thrown in her face and the show is set in Florida. Hey guys! I've had ~~such~~ a hard time memorizing periodic trends but I finally cracked the code.
