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 ...

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.

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 ...

Physicists develop a 'nuclear periodic table'. While the traditional table is based on the behavior of electrons in an atom, this new table is based on the protons in the nucleus. Protons have ...

First 20 Elements Of The Periodic Table: The atomic number and symbols are important in chemistry. The atomic number of elements gives us an idea about the atomic structure of elements, such as how ...

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 ...

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 ...

This stability seems partly connected to the mass of the atom, with heavier elements proving less stable ... "The idea was that protons and neutrons sit in shells, a bit like the electrons in an atom, ...

For new, human-made heavy elements on the periodic table, being “too ‘big’ for your own good” often means instability and a fleeting existence. The more protons and neutrons scientists squeeze ...

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 ...
