Physicists are finalizing plans for MATHUSLA, a powerful new addition to CERN's Large Hadron Collider that will detect ...

Since its inception in 2008, the LHC (large hadron collider) at CERN has been a key player in pushing the boundaries of ...

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 ...

Photo: Niels Bohr's research notes for his new atomic theory Rutherford's find came from a very strange experience. Everyone at that time imagined the atom as a "plum pudding." That is, it was ...

Atoms are very small. They have a radius of around 1 × 10 10 metres. This symbol shows that chlorine has 35 particles in the nucleus (protons and neutrons), 17 of which are protons. It also tells ...

Everything we can see and touch, and quite a lot that we can’t as well, is made of tiny particles called atoms. Some substances, like particles of this iron, contain only one kind of atom.

Recently, a team of researchers from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences (CAS) ...

According to our knowledge of the formation of atoms, the primary particles of ultra-high-energy cosmic radiation can consist of all elements from hydrogen to iron.
