Why do some elements decay in minutes, while others last billions of years? Certain "magic numbers" of nuclear particles may ...

If you hit an atom's nucleus hard enough, it will fall apart. But exactly how it falls apart tells us something about the internal structure of the nucleus and perhaps about the interior of neutron ...

Are the fundamental constants really constant? Recent investigations have shown that one essential fundamental constant -- namely the mass ratio of protons to electrons -- can have changed only by a ...

Mrs Roberts: What do you think you're made of? Mr Spellman: Big question. Grit, determination, hard-working, handsome, charming, funny. Mrs Roberts: Well, I guess. But you're actually made of atoms.

Use a concept map to review atom-related terms. Concept maps are a way to visually show how the parts of a system relate to one another. In a concept map, nouns are used to describe the components of ...

For surfers, it's not enough just to wait for the right wave: they still have to know how to catch it. As it turns out, one challenge faced by surfers also applies to protons. An experiment recently ...

A staple in every science classroom is the periodic table of elements, and for many it is their first introduction to the vast mysteries of the natural world. Now physicists from Kyoto University have ...

First 20 Elements Of The Periodic Table: This article will give the students insights into the first 20 elements of the periodic table and they can get to know about its importance. Read the full ...

An international team of researchers has discovered a new configuration of nuclear particles that decays by kicking out individual protons. With 85 protons and just 103 neutrons, the atomic nucleus is ...

The universe was too hot for atoms to form immediately after the Big Bang. Hydrogen formed about 3 minutes after the Big Bang. Helium formed in smaller amounts than hydrogen. Neutral atoms formed ...
