:: Where my nose? :: Hilang case ::
April 23, 2007
*sniffles* My nose ran away :( ... Gah = = Been having runny nose since yesterday... Can't blame it though ._. Body's been screaming "I need sleep, you stubborn girl!" these past few days. Ehh... don't look at me; blame the teachers for giving so much homework and assignments that made me feel lazy and hence procrastinate ._. Hmm? Doesn't sound right? Sounds perfectly fine to me, doood ._.
What happened today during Chemisty class gives a whole new meaning to the phrase, "Don't be afraid to try something new". We were conducting an experiment to study the reactivity of Group 1 elements of the Periodic Table.
Materials : Lithium, Sodium, Potassium, and water.
Apparatus : Basin, tweezers and eyes [ Preferably still attached to your head ._. ]
All the groups did Lithium and Potassium first and left the Sodium [ in cubes contained in a bottle ] for last because... well, both of the former ones were already precut :P You know a situation where everyone gathers around to spectate a happening? The class monitor was deciding whether to dump the whole Sodium cube into the water or to wait for teacher's further instructions, but clearly she was bias to the whole dump-it idea and carried it out anyway despite her friends' warnings. Off the cube went into the basin of water and fizzled vigorously it did. It all ended with KABOOM!... ._. Okay, just exaggerating. Anyway, it gave off some flares and a loud pop followed. Seriously, you should have seen the shock on everybody's face ._. And yep, it stinked. What happened next? I'll leave that to you :P Classic.
Ooh and teacher was explaining the reason the reactivity of alkali metals increases when going down Group 1.
The single valence electron in the outermost occupied shell becomes further away from the nucleus. Hence, the attraction between the nucelus and the valence electron becomes weaker. Therefore, it is easier for the atom to donate the single valence electron to achieve the stable electron arrangement of the atom of the noble gas.
._. ... Does that satisfy this 'equation'? : An angry man stabilizes when he gives you a piece of his mind... XD
Meh, mum's nagging - -
