When building an atom, pay close attention to the particles' electrical charges. Protons have a charge of +1. Electrons have a charge of -1. Neutrons are neutral, as its name implies. A stable atom ...

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

Japanese scientists have made a new (nu?) periodic table organized by the number of protons in the nucleus instead of the element’s number of electrons. They call it the Nucletouch table, and where ...

Part of Physics (Single Science) Unit 1: Atomic and nuclear physics Protons and neutrons are the heaviest particles in an atom and as a result they make up most of its mass. The mass of electrons is ...

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 ...

The movement of protons through electrically charged water is one of the most fundamental processes in chemistry. It is ...

Physicists have observed that a proton’s excited states, or resonances, remain influential even when probed at very high energies, a finding that revises previous expectations about the building ...

Mirror magic: The "cores" of the exotic nuclei oxygen-22 and silicon-22 both resemble that of oxygen-16, with eight protons and eight neutrons. The neutron-rich oxygen isotope contains an additional ...
