An unknown gaseous element X produces the following PES data.
Binding energy (MJ mol⁻¹) Relative peak height
0.50 2
0.80 2
3.2 6
11 2
Assuming the two lowest-binding-energy peaks correspond to valence electrons, what is the most probable oxidation state of the most stable ion formed by element X?
(a) +3
(b) +4
(c) +2
(d) −2
