An examination of common oxidation states reveals that excepts scandium, the most common oxidation state of first row transition elements is +2 which arises from the loss of two 4s electrons. Prior to that, she lead and published a number of research studies and lectured at SF State University. All the transition elements are metals. As the number of elecrons in an atom increases, we begin to see some strange behaviors. Generally, d-block elements are called transition elements as they contain inner partially filled d-subshell. 1 st Series of Electronic Configuration. acquiring half filled or fully filled 3d sub shell, it is given priority as Transition elements include d block and f block elements. These elements belong to the 0 (zero) group of the periodic table. Chemistry of Transition And Inner-Transition Elements.

According to Aufbau principle, the electron first The atoms of these elements have completely filled shells. The steady decrease in the atomic and ionic radii of lanthanide elements with increasing atomic number is called Lanthanide contraction. Many scientists describe a "transition metal" as any element in the d-block of the periodic table, which includes groups 3 to 12 on the periodic table. According to Aufbau principle, the electron first fills the 4s orbital before 3d orbital. IUPAC defines transition elements as an element having a d subshell that is partially filled with electrons, or an element that has the ability to form stable cations with an incompletely filled d orbital. periods 6 and 7, (except La and Ac) the configuration includes ( In general the electronic configuration of these elements is (n-1)d1–10 ns1–2.
