Quiz6: The properties of The First Transition Series

Using a catalyst in a reaction leads to an increase in:

2H₂O_2(L)  >>> 2H₂O_(L)+ O_2(g)     

this reaction without catalyst is slow reaction Give reason :

What is the element which attracted to magnet more than 21Sc and less than 23V in atomic state

The correct order according to the force of magnetic attraction to magnet will be:

The correct order of these compounds according to magnetic moment is ……..

The magnetic moment in cobalt ion in (CoF6)^2-

Which copound contains a diamagnetic ion formed by losing electrons from s-sublevel equals to lost electrons from d-sublevel

The atomic number of an element that its magnetic moment =2 is ……

The Atomic number  of an element its magnetic moment =3bin its oxide of formula X₂O₃ is …..

you have A,B and C  successive elements in the 1^st. transition series and the three elements are found in the same group so , their order according to magnetic moment in oxidation state (2+) is ….

A and B are 2 successive transitionn elements are found in the 4^th period where  B3+ contains two upaired electrons in d-sublevel the group which contains the element (A) is ………

Elements (X) of group VIIB which of the following oxidation state gives the highest magnetic moment for it ?

If (X) is a transition element from 2^nd transition series and in 5^th column in periodic table so magnetic moment of it in X₂(SO₄)₃ = …….

Element (X) from third transition series found in group IVB so choose the most ion attracted to the magnet:

In atomic state magnetic moment of electrons in 3^rd column in periodic table is …….. that elements of third column of d-block :

Element  (X) from 1^st  transition series found in 1^st column of group (VIII) so this element is …. If compared with the previous element in the same period:

……. Of 3+ ion of an element in group VIIB is …… than that of the ion 3+ of an element of group IIIB.
