the day i didnt sleep

Now is 6.08am(1-12-2009), after came back for Aaron's house(about 5am),i just cann't fall asleep or maybe i don't want sleep anymore...After removing some software that cause my laptop lagged, i feel nothing to do...boring...later 7.00am need wake up our beloved Best 5 's dad, then 7.30am need wake up my lovely master... haiz~~~(1st time)

Now is already 6.15am, after 6 hours i'll have my writing for science test, while 12 hours later, i will meet my chemistry test...haiz~~~(2nd time)

Erm~~~what i am doing now??? Actually i also don't know... studying chemistry???ok la... try to memorize some concept...

1.size of atom increase, when going down Group 1& 2

*the nuclear charge & screening effect increase ==>no. of proton & electron increase

*screening effect>>nuclear charge==>no. of shells increase

*attraction between nucleus & electron cloud decrease

~~~atomic size increase

2. size of atom decrease when going across the Period

*no. of proton and nucleus increase but screening effect does not change

*effective nuclear charge increase

*added electron feels a greater and greater +ve charge

*electron cloud are pulled closer to nucleus

~~~atomic size decrease

haiz~~~(3rd time)boring...

sry...just fell asleep just now...erm...7.05am now,is time to call Aaron now...bye bye...

haha...just called Aaron, seem blur blur...
