Why elements from the 2º and 3º transition series are much more alike than those from the
1º?
to the answer, yes
Solution
Q.
Alkalinity depends upon how easily an element can donate an electron from its outermost shell.
As we go from top to bottom in a column in the periodic table atomic number as well as atomic
radii increases so the distance between the nucleus and the outer shell electron increases and
makes it easier for the element to donate that electron.
Similarly in case of transition elements when we go from 1st to third row the electron donating
capability increases which thereby increases the alkalinity.
For the above reason 2nd and 3rd row transition elements are more alkaline than 1st.
