Multi-electron atoms

Postby 605136321 » Sun Oct 20, 2019 10:11 pm

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

Yea, multi-electron atom refers to all atoms outside of Hydrogen

The following are some that are isoelectronic to the H atom: He+, Li2+, Be3+ and B4+.

Some ions have only one electron, such as He 1+ or Li 2+.

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.

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.

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.

What additional factors effect electron energy in multi-electron atoms?
