FORCE & ENERGY

The forces at work are:

Electromagnetic:

Repulsion of like charges: proton-proton and electron-electronAttraction of unlike charges:proton-electron.

Magnetic:

Electron spin introduces magnetic forces. Electrons with opposite spins produce opposite magnetic poles. Opposite magnetic poles attract. Opposite spin is required for electrons to occupy the same orbital.
