write the name of two important variable factors of transition metals that may see the changes in reactions involving transition metals
Answers
Explanation:
transition metal (or transition element) has three possible definitions:
The IUPAC definition[1] defines a transition metal as "an element whose atom has a partially filled d sub-shell, or which can give rise to cations with an incomplete d sub-shell".
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.[2][3] In actual practice, the f-block lanthanide and actinide series are also considered transition metals and are called "inner transition metals".
Cotton and Wilkinson[4] expand the brief IUPAC definition (see above) by specifying which elements are included. As well as the elements of groups 4 to 11, they add scandium and yttrium in group 3, which have a partially filled d sub-shell in the metallic state. Lanthanum and actinium in group 3 are, however, classified as lanthanides and actinides respectively
Answer:
During a reaction of transition metal , mostly , we observe a change in its oxidation number and magnetic behaviour .
