Asked by Sam

how do i figure out the valences for elements in the transition elements section in the periodic table of elements (i need it for doing nomenclature) and how do i figure out the valences if i don't have the periodic table of elements

examples:
Zn
Cu
Ni
Co
Fe
Mn
Cr
V
Ti
Sc
Answered by DrBob222
Zn is almost always 2 as its placement in the periodic table would suggest. Same for Sc at +3. All of the others are variable. At least ONE valence will be the period; for example, Mn has bunches of numbers but +7 is one of them. Cr has several but at least one of them is +6. Ti has two but at least one of them is 4.
