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 ...

Why does changing just one proton in the nucleus of an atom create a different element? The number of protons in an atomic nucleus determines the number of electrons needed for a neutral atom, ...

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 ...

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 ...

Kyoto, Japan -- 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 ...

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 ...
