Frequently Asked Questions (FAQs)
Q1. Which elements are known as d Block Elements?
Sol. The elements having partially filled d-orbitals in either ground state or in at least one of their ions are termed d-block elements or outer transition elements. The d-block elements are found amidst the period table.

Q2. What are the properties of d- block elements?
Sol. The elements with halfway filled d-subshell are named as D-block elements. They are additionally named as transition elements. The inadequate subshells incorporate the (n-1) d subshell. All the d-block elements have a similar number of electrons in the peripheral shell. Henceforth, they demonstrate comparable chemical properties.
The transition elements can be either regular transition elements or the non- typical transition elements. Elements of II B group Zn, Cd and Hg have a totally filled (n-1) d subshell and henceforth, can't be incorporated into the D-block. Be that as it may, they indicate properties, for example, development of complexes with ligands, for example, ammonia, amines and halide particles and are consequently, examined alongside d-block elements. Essentially, the elements of group III-A Sc, Y, La, and Ac vary from other d-block elements, however, have a not entirely filled (n-1)d subshell and are consequently, considered alongside d-block elements.
These elements that is, elements of group II B Zn, Cd and Hg and III A Sc, Y, La and Ac are named as non- typical transition elements and the other transition elements are named as typical transition elements.
The d-block incorporates three arrangements each of ten elements. These arrangements are described by the totally filled 3d, 4d, and 5d subshells and are named as 3d-(first series) Sc - Zn, 4d arrangement (second series) Y-Cd and the 5d arrangement (third series) La-Hg separately. There is a deficient fourth series comprising of just three elements in particular Ac, Ku, and Ha. In these elements, the 6d subshell begins to fill at Ac.
Q3. Which transition metals can be used to make magnets?
Sol. Iron, cobalt and nickel
Q4. Where are the transition metals found in periodic table?
Sol. The 38 elements in groups 3 through 12 of the periodic table are called "Transition Metals." As with all metals, the transition elements are both malleable and ductile, and are good conductors of electricity and heat.
