Hawaii Volcanoes
The Island of Hawaii is made up of five volcanoes. Each began to grow beneath the sea and eventually joined to form a single island. The volcanoes grew from a hotspot beneath the sea. The chain of volcanoes were created as the Pacific Plate moved...

Alan Pease, author of a book titled "Why Men Don't Listen and Women Can't Read Maps", believes that women are spatially-challenged compared to men. The British firm, Admiral Insurance, conducted a study of half a million claims. They found that...
Should We Fear Death?
Death is not something that many people want to think about.
However, death is a part of living a human life. At least, our
current level of science and technology acknowledges that death
is inevitable.
Is death something to be afraid of or...
Webcams: Science Fiction Communication at Home
One of the most incredible inventions I�ve ever come across is the web cam and its process of video conferencing. This is just so futuristic I can�t believe they really exist and are readily available to anyone with the Internet, speakers, and the...
Would You Care To Be Digitized?
How is it to be digitized?
Gibberish speaking, digitize, as explained in the field of
computer science, is the conversion of any continuously
different source of input, i.e., lines in a drawing, or a signal
of sound, into a series of hidden...

A cluster of atoms
Imagine a new variety of compounds; compounds that have properties never seen before or simply compounds that have properties more pronounced than those which we already know of at present. It would be really cool. No, in fact it is really cool! Indeed, an entirely new class of compound is on the verge of getting everybody�s attention.
Only some times back, it has been shown that a new division of compounds could exist. A new study now confirms the idea that a cluster of atom of an element, behaves differently from a single atom of the element. It is as if, a new element is being created.
For example, a cluster of 13 aluminium atoms behaves like a halogen (chlorine, bromine, iodine, etc). In addition, the aluminium cluster can react with halogens to form halogen compounds with novel properties!
However a cluster of one more aluminium atom, that is to say, 14 aluminium atoms, will act not like a halogen but rather like an alkaline earth (calcium, barium, etc) atom. And the ions that are hence formed are in fact totally new types of salts! For instance, when the 14 aluminium
atom cluster reacts with 3 iodine atoms, an ion with an absolute charge of �3 is formed. Surprisingly this resulting ion is very stable.
The atom cluster thing has also been a source of debate in the scientific community. According to Shiv Khanna, co-leader of the study, the periodic table must be altered to accommodate the clusters or �superatoms,� as he calls them.
How? Simple. Just add a 3rd dimension to the periodic table. The 13 aluminium atom cluster will then be in the same row and column as iodine since it acts more or less like the latter. Only difference is that it will be in a new plane. Same thing for the 14 aluminium atom cluster in the alkaline earth group and for the other �superatoms.�
As if the periodic table wasn�t complicated enough! But I guess that it will be even more so if the additions are made. So don�t you dare think that your generation�s college chemistry was hard!
