Question

Describe the main difference between the 2nd and 3rd row transition elements

Answer 1

The transition metals, groups 3–12 in the periodic table, are generally characterized by partially filled d subshells in the free elements or their cations. (Although the metals of group 12 do not have partially filled dshells, their chemistry is similar in many ways to that of the preceding groups, and we therefore include them in our discussion.) Unlike the s-block and p-block elements, the transition metals exhibit significant horizontal similarities in chemistry in addition to their vertical similarities.

Answer 2

Answer:

Below are many difference.

Explanation:-The first main transition series begins with either scandium (symbol Sc, atomic number 21) or titanium (symbol Ti, atomic number 22) and ends with zinc (symbol Zn, atomic number 30). The second series includes the elements yttrium (symbol Y, atomic number 39) to cadmium (symbol Cd, atomic number 48). The third series extends from lanthanum (symbol La, atomic number 57) to mercury (symbol Hg, atomic number 80). These three main transition series are included in the set of 30 elements often called the d-block transition metals. Because scandium, yttrium, and lanthanum actually do not form compounds analogous to those of the other transition metals and because their chemistry is quite homologous to that of the lanthanoids, they are excluded from the present discussion of the main transition metals.

More Difference-The transition metals, groups 3–12 in the periodic table, are generally characterized by partially filled d subshells in the free elements or their cations. (Although the metals of group 12 do not have partially filled dshells, their chemistry is similar in many ways to that of the preceding groups, and we therefore include them in our discussion.)
