Answer:
Option C : Ag
Electronic configuration:
47Ag: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d9
The d-block elements are present in the middle of periodic table between s and p-block elements. d-block elements are also called Transition elements. Their valance electrons are reside in the d orbitals. They have more electropositive character than p-block elements but less than s- block elements.
Answer: C) Ag is a d block element
The correct option that tells about the element present in the block is option C.
Explanation:
We know there are different energy levels present inside the atoms and orbitals s,p,d,f are the reason behind the difference between the elements that marks different blocks. The s and p blocks are the middle area that is what makes D block.
There are many elements present the within the D block and silver among the given options is the only one that belongs to this group. Some other are iron chromium copper etc.
