Matter is made up of very small parts called atoms. Atoms can combine in different numbers and in different ways to make different molecules. Atoms and molecules make up all of the different ...

Since their advent, they have helped scientists see structures as small as individual atoms. But they suffer from a fundamental drawback — to image individual atoms, samples have to be placed in ...

Now you know that atoms are really small and that there are huge numbers of them, but here are a few other atom facts you might find interesting. Where do atoms come from? Believe it or not, the atoms ...

We know that matter is made up of particles called atoms and that an element is a substance that is made up of only one kind of atom. But what are atoms made up of? A very important part of ...

Atoms are the building blocks of everything. Atoms can form strong bonds with each other, making molecules. Symbols and formulae Letters from the alphabet are used to represent chemical elements ...

For the first time, researchers have captured nanoscale video footage of hydrogen and oxygen atoms combining into water out of "thin air" — thanks to a rare metal catalyst. The super-efficient ...

(The atom is then called an ion). Do not allow your atom to become too ionized. Ions are attracted to other atoms and molecules. If your atom is too ionized, it will likely zip away from you and ...

In crystallography, angstroms are used to measure the distances between atoms in a crystal lattice. X-ray diffraction techniques can determine the arrangement of atoms in a crystal by measuring the ...

In an experiment at the Max Planck Institute of Quantum Optics, in cooperation with planqc, the researchers succeeded in setting up a register of 1,200 atoms in an optical lattice of laser light ...

Iron is absorbed in the gut and transported into plasma by an apical divalent metal transporter, DMT1, and a basolateral transporter, ferroportin. Only 1–2 mg of iron is absorbed per day in the gut.

But until now the elusive substance has been almost impossible to analyse because its atoms move around so much. Now scientists have a workaround - freezing it with lasers. "Physicists are in love ...

The problem in this case is the formation of a poorly soluble calcium salt of ceftriaxone, the ionized form of which is a divalent anion. [9] The general basis for this divalent cation-divalent ...
