so the periodic table may never be complete. These manmade elements are created using particle accelerators thatsmash atoms and subatomic particles together, generating nuclei with extra protons and neutrons. However, these ultra-heavy elements are highly unstable and difficult to make. “We really ...
How Nuclear Radiation Works describes protons, neutrons and electrons in some detail. For example, hydrogen atoms have one electron orbiting the nucleus. Helium atoms have two electrons orbiting the nucleus. Aluminum atoms have 13 electrons circling the nucleus. Each atom has a preferred number of ...

coli was present in ≥50% of invasive isolates [16]. Such high percentages of E. coli resistance to these compounds are concerning, as the Gram-negative E. coli is the dominant bacteria responsible for many common human diseases, including, but not limited to, urinary tract infection (UTI)...
usually in the blue or green region of the spectrum. Sometimes, the luciferin binds with a catalyzing protein and oxygen in a large structure known as aphotoprotein. When an ion -- typically calcium -- is added to the photoprotein, it oxidizes the luciferin, resulting in light and inactive...
Neutrons are an important tool in cultural heritage studies, as they are non-destructive and can penetrate deep into solid or, uniquely, liquid materials to reveal what is happening at the atomic or molecular level. They can re...
