Hello,

I am so confussed..

Talking about transition metals, in the book it says that the general trend in a period is for the metallic radii to decrease due to increase of Zeff. But I don't think this makes sense.

I think: we are talking about metallic radii not IONIC!!!! If its metallic, then the radii would be half the distance between the two metals. hence, the greater bonding, the smaller de radii. Hence, as the period goes by and the orbitals become more contracted, less bonding, GREATER RADII!!!!

why am i wrong?
please *delete me*!
