New particle Xicc++ -- properties

[arusse02]

I was wondering what kind of properties the new particle detected from the LHC would have? For example is the particle charged? Could an electron orbit it and is it a stable enough particle to be able to participate in chemical interactions? What else is known?

It is charged, it has +2 elementary charge, that's where the "++" name part comes from. -2 elementary charge for its antiparticle (LHCb studied both together).

In theory the positively charged one could capture two electrons and behave similar to a helium atom for a very short time, which means no chemical reactions. It could also be part of a nucleus and increase its charge by +2.
In practice we don't have electrons around it could capture.
