10.Why is it difficult to study about a single Atom?
Answers
Answer:
In the quest to shrink data storage down into tinier and tinier forms, scientists have scored a very, very small triumph.
They did it by creating what’s essentially an incredibly diminutive magnet: It’s just one atom in size, and while it’s not going to be holding birthday cards up on your refrigerator anytime soon, it can do something else: store a data point.
Described in the journal Nature, the experiment involved atoms of a rare earth element called holmium. Physicists working at an IBM research facility in California found that when the holmium atoms were placed on a special surface made of magnesium oxide, they naturally oriented themselves with a magnetic north and south pole—just like regular magnets have—pointing either straight up or down, and remained that way in a stable condition. What's more, they could make the atoms flip by giving them a zap with a scanning tunneling microscope that has a needle with a tip just one atom wide.
The experiment mimics the way the magnetic disk of a hard drive works. Tiny magnets on those disks point either up or down, and that orientation conveys binary information—either a one or a zero. The bits of information on hard drives are physically much bigger though: they’re made up of about 100,000 to a million atoms. The bits in the IBM experiment are miniscule.
Answer:
because it is chemistry subject . an atom is indivisible and cannot be created not be destroyed.
so it is difficult
