can u tell me the important reaction of d block elements of class 12th??
Answers
Answer:
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 first three rows of the d block elements which correspond to the 3d, 4d, and 5d orbitals, respectively are given in the below article.
What are D Block Elements?
What are D Block Elements?Elements having electrons (1 to 10) present in the d-orbital of the penultimate energy level and in the outer most ‘s’ orbital (1-2) are d block elements. Although electrons do not fill up ‘d’ orbital in the group 12 metals, their chemistry is similar in many ways to that of the preceding groups, and so considered as d block elements.

Although electrons do not fill up ‘d’ orbital in the group 12 metals, their chemistry is similar in many ways to that of the preceding groups, and so considered as d block elements.These elements typically display metallic qualities such as malleability and ductility, high values of electrical conductivity and thermal conductivity and good tensile strength. There are four series in the d block corresponding to the filling up of 3d, 4d, 5d or 6d orbitals.
Answer:
The atomic number of the element is 11. Hence it contains 11 protons and 11 electrons since the element is neutral. Its mass number is 23 and hence it contains (23-11) = 12 neutrons.
