In atomic physics, a two-electron atom or helium-like ion is a quantum mechanical system consisting of one nucleus with a charge of Ze and just two electrons. This is the first case of many-electron systems where the Pauli exclusion principle plays a central role. It is an example of a three-body problem. The first few two-electron atoms are: (Wikipedia).

How Do Atoms Bond - Part 2 | Properties of Matter | Chemistry | FuseSchool
Learn the basics about how atoms bond when learning about the structure of atoms. Bonds form by the attraction of negatively charged electrons and the positive nucleus of atoms. Atoms have a positively charged tiny nucleus which contains almost all the atomβs mass, surrounded by shells o
