What is the valency of promethium?
Promethium is an element and does not have a charge. As it has only be found in trace quantities, its chemistry has not been fully investigated. It has been anticipated that the likely charge when it forms compounds would be +3.
What is the charge of samarium?
The atoms of the element samarium (atomic number 62) have the electron configuration [Xe] 4f6 6s2
What is the charge of a Xe ion?
1.what is the oxidation state in xenon in HXeO4- and ... xenon is +7. As= +3 ... Xe = +7. As = +3 ... Except when highly electropositive elements are involved
What is exnon?
Xenon = Xe xenon, Xe, 54
When was Xe-NONE created?

How do you draw the Lewis structure for XeF2O?
Xe would be your central atom, O is attached to it by a double bond and your two Fs are attached be a single bond. There would be 3 Lone Pair (LP) electrons around F, 2 around O, and 2 around Xe. Why ? There is no valance to this molecule so you want to satisfy the formal charge to be 0. Formal charge = (#electrons in ground state) - [ (free electrons) - 1/2 (bonding electrons)]. Formal charge for F, would want 0 so 0 = 7 - [? + 1/2 (2) ] = 7 - (? +1) = 7 - ? - 1 ? = 6, therefore 3 lone pairs around fluorines. Formal charge for O, would want 0 so 0 = 6 - [? + 1/2 (4) ]... ? = 4, therefore 2 LP around oxygen Formal charge for Xe, again we want it to be 0 so, 0 = 8 - [? + 1/2 (8)]..... ? = 4, therefore 2 LP around Xe. Kind of a weird set up (since Xe does not follow the octect rule), but it works out =)
