Reactivity Series of Metals

Here’s a nice mnemonic to aid in learning the reactivity series of metals:

Popular Potassium K
Scientists Sodium Na
Can Calcium Ca
Make Magnesium Mg
A Aluminium Al
Zoo Zinc Zn
In Iron Fe
The Tin Sn
Low Lead Pb
Humid Hydrogen [H]
Country Copper Cu
More Mercury Hg
Satisfactory Silver Ag

Note that this may differ from many lists, especially since some rate calcium above sodium. And do remember to add gold and platinum, in that order, at the bottom (although there’s confusion over this too since platinum is sometime’s placed higher). If you want, you may put lithium at the top, but then again, there’s controversy since some put it below potassium.

Anyway, this has been a real help for me whenever I’ve been doing chemistry, so putting this here for the rest of humanity (or whichever lucky part of it is reading my blog). The reason why this one (I feel) works better is because it tries to build up a relation from the common names of elements, rather than their scientific names, which messes up other such mnemonics.

Interesting thing though, that something like a mnemonic, which is supposed to aid learning, itself will knot up your tongue if you try to pronounce it. 😉

GeoShities

Although I’m a devoted fan of Yahoo!, I do like the occasional parody and the one I reveal to you now is just too damn good. It’s a parody of Yahoo! GeoCities service, called Yapoo! GeoShities, which you MUST visit!

The page is well-made and hilarious, more so if you’ve actually visited the actual GeoCities page since the page layout, colors, images, everything down to the last thing is the SAME (although recently Yahoo! changed the GeoCities main page, so it won’t resemble now). Read every part carefully, and soak in the heavenly sarcasm. And the best thing is that it actually links to the real Yahoo! pages as on the proper site.

Do visit the older GeoShities pages too, the link to which you’ll find at the bottom of that page. On those archived pages too, have a look at the links at the bottom and the way Yahoo! has been parodied.

Tell me if you liked it. 😉 I did!
