Thulium has an electronic configuration of [Xe] 4f136s2
You could count either 2 or 15. The concept of valence electrons is almost meaningless when applied to the lanthanides. Thulium is a typical member of these and has one common oxidation state, +3
The thorium valence is +4; only in the difficult to obtain ThO the valence is +2.
Three valence electrons.
It has 69 protons and electrons
Thorium has four valence electrons.
