Interpretation Introduction

(a)

Interpretation:

The given decreasing order of atomic radii (Sc>Ti>V) needs to be explained.

Concept introduction:

The atomic radii can be described as the distance between the nucleus and the boundary of the electron's outer shell. It is also used to measure the size of the atom.

Interpretation Introduction

(b)

Interpretation:

The given increasing order of density (Ti<V<Cr) needs to be explained.

Concept introduction:

The density of the substance can be described as the relationship between the mass of the substance and the volume of the substance. It is mathematically represented as follows:

d=mV

Here, m is mass and V is volume.

Students have asked these similar questions

(a) Calculate the number of unpaired electrons in the following gaseous state ions: Mn2+, Cr3+, V3+ and Fe2+ which one of these in the most stable in aqueous solutions? (At. nos. V = 23, Cr = 24, Mn = 25, Fe = 26) (b) Explain the following observations: (i) The transition metal ions are usually coloured in aqueous solutions. (ii) Cu(I) is not stable in an aqueous solution. (iii) The highest oxidation state of a transition metal is exhibited in its oxide or fluoride.

State reasons for the following observations: (i) The enthalpies of atomisation of transition elements are quite high. (ii) There is a greater horizontal similarity in the properties of the transition elements than of the main group elements.

How would you account for the following :(i) Among lanthanoids, Ln (III) compounds are predominant. However, occasionally in solutions or in solid compounds, + 2 and + 4 ions are also obtained.(ii) The E°M2+/M for copper is positive (0.34 V).Copper is the only metal in the first series of transition elements showing this behaviour.(iii) The metallic radii of the third (5d) series of transition metals are nearly the same as those of the corresponding members of the second series.
