Question 1
1 / -0

Which of the following statements is incorrect?

A
Besides the common +3 oxidation state, actinoids can exhibit +4, +5, +6 and +7 oxidation states.

B
Actinoids are less basic than lanthanoids.

C
Actinoids are radioactive.

D
Actinoids have a greater tendency for complex formation.
Question 2

A
Cobalt

B
Copper

C
Chromium

D
Nickel

Solution

Cu, Ag, Au are known as coinage metals. The elements of Group 11 are being called the coinage metals.
Question 3
1 / -0

Which of the following is not a coinage metal?

A
Copper

B

C
Gold

D
Platinum
Question 4
1 / -0

4d transition elements series are from

A
Sc to Zn

B
Ce to Lu

C
Y to Cd

D
La to Hg

Solution

4d series arises from Y (4d¹ 5s²) to Cd (4d¹⁰ 5s²)
Question 5
1 / -0

In which of the following species is manganese in the lowest oxidation state?

A
Mn₂O₇

B
MnO₄^-

C
MnO₄^2-

D
MnF₄
Question 6
1 / -0

The f – block elements are known as

A
Representative elements

B
Inner transition elements

C
Transition elements

D
Inert elements

Solution

The elements in which the valence electron enters in anti penultimate energy level i.e., (n - 2) f are known as f - block elements.This name is because of the position of the valence electron is in the f - orbital.Since the last electron enters into (n - 2)f - orbital which is inner to the penultimate shell (For d-block elements), they are also called inner transition elements

A
Successive shrinkages in the atomic size are referred to as lanthanoid contractions.

B
Actinoids are more reactive than lanthanoids.

C
Salts of La³⁺ and Lu³⁺ are colourless.

D
Eu²⁺ and Yb²⁺ are good oxidising agents.
