I think that you're explaining this(4s=3d in terms of valence electrons) bcoz of the variable valency shown by d-block elements..

Sorry to say Sir….but 4s is not the same as 3d..
So both can't be treated equally as valence electrons(practically)…
The outermost shell 4s may be treated as valence shell..
