Particle-accelerator study focuses on the r-process thought to be responsible for forming elements heavier than iron ...

“At low temperatures, models of reactivity must include the effects of the permanent electric dipoles and quadrupole moments ...

Primordial helium from the beginning of the solar system may be stuck inside Earth's solid core, new research suggests. The ...

So in the helium example, there would be four protons and two electrons in the nucleus to yield a mass of 4 but a charge of only 2. Rutherford also put out the idea that there could be a particle ...

An alpha particle consists of two protons and two neutrons and is often described as a helium nucleus. It is not the same as a helium atom as it does not contain any electrons but it is written ...

The atom with eight protons in its nucleus (atomic number 8) is oxygen. Each energy level holds a certain number of electrons before electrons go into the next level. 1st Period: Hydrogen and ...
