Why matter dominates over antimatter in our universe has long been a major cosmic mystery to physicists. A new finding by the ...

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 ...

But while the LHC has proven a success when it comes to the Higgs, whose existence was confirmed by CERN scientists in 2012, ...

After tracing many particles and examining the patterns, Rutherford deduced that the atom must have nearly all its mass, and positive charge, in a central nucleus about 10,000 times smaller than ...

This symbol shows that chlorine has 35 particles in the nucleus (protons ... as the number of electrons and protons are equal in a neutral atom, chlorine also has 17 electrons.

Scientists trying to discover the elusive mass of neutrinos, tiny "ghost particles" that could solve some of the universe's ...
