is there periodic table with the valence electrons written for each element? 3D model of Periodic Table of Elements. A more current Periodic Table will show that there are close to 120 listed elements. Most of the elements after Radon are radioactive, created in labs, or collected after setting off a nuclear bomb. This brings the final chain in the 3D model to 32 rather than 24/25. Note, the most polarized element Neodymium is located in the center of the table. There is a similarity of the structure here to the tree of life: hydrogen at the center, 6 noble gasses ...
Question : Here is the question on my homework. 'State a hypothesis to explain why the atomic radius of the transition elements changes very little on your graph (clue the d-orbital is involved)'
I've tried google and wikipedia and nothing has helped so hopefully someone here can help me.
Thanks.
Answer : the 'additional' electron for each successive element enters the the inner 3d sub shell where it provides a more effective shield between the nucleus and the outer 4s sub shell. hence, although each successive nucleus has one more proton, the extra positive charge is partly shielded by the extra electron in an underlying 3d sub shell.

Question : I know that for representative elements, you can just look at the group number for the valence electrons, but what do i do for the non-representative elements like the transition metals?
Answer : The valence configuration of the transition metals is unusual because they all technically have 2 valence electrons but they will promote out of the d orbital up into the next energy orbitals. Even with in the same element there can be differences in valence electron number The oxidation number of the the transition metals can be used to find the number of valence electrons. For example copper can be either +1 or +2, this means that it loses either 1 or 2 electrons. So copper either has 1 or 2 valence electrons.
