In a given transition series, there is no signifiecant change in the atomic radii of elements with increse in atomc number. Explain why.

The number of transition series is:

The atomic radii of transition elements in a period are.

State the following: How do the atomic radii change in a period with increasing atomic number?

In a transition series, as the atomic number increases, paramagnetism

In the transition series, with an increase in atomic number, the atomic radius does not change very much. Why is it so?

Why are the atomic masses of most of the elements not whole numbers ?

Why are transition elements so named ?

The correct order of atomic radii in group 13 elements is

What is the name given to elements with same mass number and different atomic number ?

Assign reason for each of the following statement: (i) The largest number of oxidation states are exhibited by the elements in their row transition elements. (ii) The atomic radii decrease in Size with the increasing atomic number in the lanthanoid series
