Iron is an element. It is made of only one type of atom: iron atoms. Sulfur is another element. It contains only sulfur atoms, and nothing else, so it is pure. When we mix two different pure ...

Researchers discover a way to potentially reduce CO2 emissions and decrease the need for chlorine to produce ethylene oxide — ...

The word magic is not often used in the context of science. But in the early 1930s, scientists discovered that some atomic nuclei – the center part of atoms, which make up all matter – were more ...

is built of elements—the different types of atoms. They’re billions of years old, most of them, scattered into space by the big bang or exploding stars, then incorporated into the newborn ...

When looking at atoms (or anything) in a quantum superposition state, it normally lasts for fractions of a second. These ...

An international team of researchers at the Karlsruhe Institute of Technology (KIT) has developed a new method for analyzing actinides. The method provides unique insights into the electronic ...

Their "failure" was, in retrospect, important evidence for the existence both of heavy water and of isotopes—atoms of an element that have the same number of protons but a different number of ...

Therefore, in the everyday world of Earth, from the peak of the highest mountain to the depths of the deepest ocean, atoms are not converted to other elements during chemical reactions.
