Which element is a d block element?
a) s
b) ar
c) ag
d) as
e) none of these elements is a d block element.

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.

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.

hope this

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)

it's filtration, but this is an assumption so my apologies if i got this
