Test: Position of D & F Block Elements (December 8) - Question 1

### Which one of the following is a diamagnetic ion?

Detailed Solution for Test: Position of D & F Block Elements (December 8) - Question 1

Co+2 = [Ar] 3d7
Cu2+ = [Ar] 3d9
Mn+2 = [Ar] 3d5
Sc+3 = [Ar]
We can see that only Sc+3  has no unpaired electron, so it is a diamagnetic ion.

### The inner transition elements are the elements in which the added electrons go to:

Detailed Solution for Test: Position of D & F Block Elements (December 8) - Question 3

The inner transition elements are the elements in which the added electrons go to (n-2) f-orbitals. These include lanthanoids and actinoids. In lanthanoids, the added electron goes to 4f orbital and in actinoids, the added electron goes to 5f orbital.

Test: Position of D & F Block Elements (December 8) - Question 4

The second series of transition element starts with:

Detailed Solution for Test: Position of D & F Block Elements (December 8) - Question 4

The second series includes the elements yttrium (symbol Y, atomic number 39) to cadmium(symbol Cd, atomic number 48).

Test: Position of D & F Block Elements (December 8) - Question 5

Which form of silver is colourless?

Detailed Solution for Test: Position of D & F Block Elements (December 8) - Question 5

ilver in the form of Ag+ is colourless. For transition metal ions to exhibit color, their metal ions must have incompletely filled (n-1)d orbitals.

Ag+ =4d10,5s0

Ag+ has completely filled d orbitals hence is colourless.

Test: Position of D & F Block Elements (December 8) - Question 6

Which among the following is colourless?

Detailed Solution for Test: Position of D & F Block Elements (December 8) - Question 6

Zn2+ has completely filled d-orbitals and there are no vacant d-orbitals for the transition of electrons, hence it is colourless.

Test: Position of D & F Block Elements (December 8) - Question 7

Melting point of d block elements across a period:

Detailed Solution for Test: Position of D & F Block Elements (December 8) - Question 7

Till d5 unpaired electron are increasing so maximum bonding as unpaired electron take part in bonding. So melting point increases till d5 then start decreasing due to pairing which decreases metallic bond strength and thus melting point.

Test: Position of D & F Block Elements (December 8) - Question 8

Which of the following group of elements are not regarded as transition elements?

Detailed Solution for Test: Position of D & F Block Elements (December 8) - Question 8

Zn, Cd & Hg because the d-orbital of these elements are completely filled. So, they don't show the characteristics of transition elements (i.e. the d-orbital of transition elements is incomplete.

Test: Position of D & F Block Elements (December 8) - Question 9

The first ionization energy of the d-block elements are?

Detailed Solution for Test: Position of D & F Block Elements (December 8) - Question 9

The first ionization energy of the d-block elements are between s and p-block elements. Thus they are more electropositive than p-block elements and less electropositive than s-block elements.

Test: Position of D & F Block Elements (December 8) - Question 10

Detailed Solution for Test: Position of D & F Block Elements (December 8) - Question 10

Since the configuration of Fe3+ ion is (argon ) 3d5,which contains maximum number of unpaired electrons, hence more will be paramagnetic behavior.
