The difference lies in the structure of the atom's nucleus ... with separate levels for protons and neutrons. Individual isotopes can correspondingly be singly magic, with a magic number of either ...

Scientists may have finally uncovered the mystery behind ultra-high-energy cosmic rays — the most powerful particles known in ...

In a new study, scientists have shown that chemical receptors that plants use to recognize nitrogen-fixing bacteria have ...

An element's atomic number defines it. An element with 17 protons will always be chlorine. However an element's mass numbers can vary, which means that it can have different numbers of neutrons. So ...

The biological study of species offers no equivalent to such transmutation. An individual which belongs to a given species ...

Low nitrogen availability is the number one limitation to plant growth in most ecosystems. Plants in the bean family and other closely related families evolved a symbiotic relationship with bacteria ...

The Nobel Prize in Physics for 2025 honors scaled-up quantum physics—while sidestepping controversies swirling around quantum ...

Atoms are the basic building blocks of matter, and understanding their composition is a fundamental aspect of chemistry and physics. One of the most crucial aspects of an atom is understanding the ...

Could black holes help explain the origins of high-energy cosmic radiation? The universe is filled with many forms of ...

For example, the atomic number of chlorine is 17. Every chlorine atom has 17 protons and 17 electrons. It has 17 positive charges and 17 negative charges, meaning that it is neutral overall. Atoms of ...

In alchemy, a theory exists about altering the nature of metals through changes in their composition, prominently featuring the legendary philosopher’s stone. But can one truly ... Continue Reading → ...
