When an electron binds to a proton, it forms a neutral hydrogen atom, with the entire system having a slightly smaller amount of rest mass than the free proton and free electron combined.

What's more energetically favorable? Having a neutral sodium atom (Na) paired with a single proton (H+), or having a sodium ion that's lost one electron (Na+) paired with a neutral hydrogen atom (H)?

This changes the boundary conditions of the Dirac equation, and surprisingly, leads to a new version of the hydrogen atom where the electron is extremely close to the proton, far closer than in ...

This charge radius cannot be measured directly but can be inferred from the hydrogen atom, which consists of a proton and an electron.

Five years later, scientists were able to peer inside a hydrogen atom using a " quantum microscope," resulting in the first direct observation of electron orbitals.

Supercomputer simulations of buckyballs with 12 lithium atoms distributed evenly on their surfaces indicate that each lithium atom would hold 10 atoms of hydrogen, Jena and his colleagues report ...

An orbital structure is the space in an atom that’s occupied by an electron. But when describing these super-microscopic properties of matter, scientists have had to rely on wave functions — a ...

Artificial atoms comprised of shells of electrons, without a nucleus present, have been used in silicon as the building blocks for quantum computers.

Take a hydrogen atom, with one proton and one electron, as a system, would entropy increase in the system over time to the point where the two particles would not function as an atom anymore?

The remaining electron then behaves as if it were orbiting a nucleus with just one positive charge, just like the electron in a hydrogen atom. The difference is that the nucleus is 4.1 times ...
