How many electrons are there in the Universe? One bold theory suggests that there could only be one, although this theory has ...

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 us ...

Chemists reveal method for differentiating PCET mechanisms -- a key step for steering fundamental energy conversion and redox catalysis processes. Redox reactions form the basis of many fundamental ...

Scientists have discovered a new way to investigate the structure of protons using neutrinos, known as 'ghost particles.' Neutrinos are one of the most abundant particles in our universe, but they are ...

In most stars, hydrogen is turning into helium, and the process starts with two protons coming together to form helium-2. This usually splits back apart very quickly, but sometimes one of the protons ...
