Lanthanides

Hi there,

So sorry, was really busy since the start of school this year. You can't imagine...

Anyway, since Tony has requested for Lanthanides, we will have, with no choice, to provide some things about it. To know why Tony is so powerful, ask any 4I '07. Haha.

Now, Lanthanides... these are the f-block elements, see the two rows that look like being 'inserted' into the Periodic Table.

Picture from http://www.dayah.com/

Let us revise... Why is Gp I and II metals called s block elements?

Li 1s2 2s1
Mg 1s2 2s2 2p6 3s2
K 1s2 2s2 2p6 3s2 3p6 4s1

See the pattern? So why Lanthanides are called the f-block?

Anyway, dun want to dwell too much, else many would have headaches. If you are really interested, I've a good website to recommend, very comprehensive. It is a course website from Oxford University Chemistry Department.

Enjoy!!

p.s. they have got some interesting mnemonics to aid you in remembering the sequence of lanthanides. Go check it out. =)

Closure of the Temple?

No way! Actually, I'm thinking of continuing this blog with discussion of A level related stuff.

However, the frequency of updating would be lower. You could help by providing me with some interesting articles or topics which you come across in your study in RJ.

Good luck and mug hard.

Chem RA - Mass Spectroscopy

Yoz ppl,

Hi. First post of the year. Must start with a bang...

This is something I'm doing with my RA Class this year. So try this if your tutorial load is not already killing you.

Sypnosis of Lesson: Mass Spectroscopy provided evidence for isotopes and can be used to identify the compounds under study. To learn more, refer to this.

Now the question is: Which spectrum belongs to which compound?


For my J1 students, you should at least know how to name these molecules right??!!

RA Students: Please come with the answer to the question. It is not optional for you. =)

Enjoy!

Last post of the year....

Yoz,

Time flies and now is the end of the year.... so here's the last post of the year.

Remember I always tell you how Pb can make u less intelligent (or more 'less intelligent' for some of u, hahahaha) and how Al can make one get Alzheimer's Disease? Now, researchers in Emory University has found that Copper ions might also have something to do with the Alzheimer's. Read here for more.

While you might not be able to understand the article fully, hopefully you will see the importance of Chemistry and that much research is actually interdisciplinary and requires collaboration between experts of the various discipline.

Ok, here's wishing all a blessed new year. Enjoy your new school.

Auspicium Melioris Aevi

Fries, with bamboo extract please..

Yoz,

Have you been having loads of chips and fries during this hols? If so, you might want to have it with some bamboo extract. Read this for more.
