Multi-electron atoms
What is a multi-electron atom, don't all atoms have multiple electrons except for H?

Re: Multi-electron atoms
The following are some that are isoelectronic to the H atom: He+, Li2+, Be3+ and B4+.

Re: Multi-electron atoms
Sometimes when atoms have multiple electrons they can lose them and end up with only one and a net positive charge. It's not super common but it can happen.

Re: Multi-electron atoms
Yes, the one-electron model is only applicable to H-atoms. All other atoms will have more than 1 electron, rendering it a multi-electron atom.

Re: Multi-electron atoms
Hydrogen is the only element that has one electron in its ground state. Otherwise, all other elements can be considered multi-electron atoms. Helium could hypothetically be stripped of an electron (even though highly unlikely/extremely difficult because it is highly stable) and become a single-electron cation.
