Question

What are dblock elements. and why it is useful plz explain​

Answer 1

Answer:

Explanation:

D block elements are the elements which can be found from the third group to the twelfth group of the modern periodic table. The valence electrons of these elements fall under the d orbital. D block elements are also referred to as transition elements or transition metals.

The d-block elements are found in groups 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12 of the periodic table; d-block elements are also known as the transition metals. The d orbital is filled with the electronic shell “n-1.” Properties of Transition Metals. Group 3: Transition Metals. Group 4: Transition MetalThey are called d block elements because the electrons being added in this block of elements are being added to the d orbitals. Look at the electron configurations for Scandium (Sc), Titanium (Ti), and Vanadium (V), the first three transition metals of the first row in the d block.
