Homework Help: Periodic Table: Transition Metals

  1. Sep 29, 2013 #1
    1. Regarding: Transition metals of the Periodic Table

    2. Here's my question: the D-Block transition metals will always lose e- (& never gain e-'s) to fully fill (or half-fill) their d-subshells, right?

    3. Given what I learned about stable, fully-filled and half-filled subshells, the teacher said the that main group elements in the P-block can form cations or anions. I'm not sure where to go from here. If anyone could help me, that would be great.

    Sometimes (n+1)s electron will jump down to nd to fill it. For example ground state of copper is 3d104s1 and not 3d94s2 that you could expect.

    Please elaborate - no idea where is the problem and where you want to go. Yes, p-block elements can form cations or anions. Indium(I) iodide comes to mind.
