but how many valence electrons does chromium have?

Name: Chromium
Symbol: Cr
Atomic Number: 24
AtomicWeight: 51.996100
Family: transition metals
CAS RN: 7440-47-3
Description: A silvery metal
State (25 ° C): Solid
Oxidation states: +2,+3,+6
Valence Electrons: 3d54s1
but apparently it can vary:
"Some elements, like the transition metals, have electron configurations in which electrons from their inner shells can also be used as valence electrons; these elements can have several different oxidation states. For example, iron can have a valence of +2 or +3, and chromium can have a valence of +2, +3, or +6.
But yikes - now I've got still another answer:
How many valence electrons does Chromium
Yes! Many Transition Metals can have different numbers of valence electrons. The "II" means it has 2 valence electrons.
and yet another:
"Because the valence electrons are defined as the electrons in the outermost or highest energy shell, for iron, that would be the 4th shell. So the 6 electrons in the 3d orbital don't count. Only the 2 electrons in the 4s orbital count since they are in the 4th shell. Most transition metals thus have 2 valence electrons (although some, such as chromium, only have one because of exceptions to the filling rules -- the configuration of chromium is [Ar]4s13d5).
OK - I give up.
