Chapter 19, Problem 19.34SP

(a)

Interpretation Introduction

Interpretation:

From the given set of elements $\text{C, Se,}\text{B,}\text{Sn,}\text{Cl}$ the element which has largest atomic radius has to be identified.

Concept introduction:

In column the ionic radii or atomic radii is always increases, as the atomic number and the size of the atom gets larger.

In period the ionic radii or an atomic radius is always decrease due to the nuclear charge increases.

(b)

Interpretation Introduction

Interpretation:

From the given set of elements $\text{C, Se,}\text{B,}\text{Sn,}\text{Cl}$ the element which is most electronegative has to be identified.

Concept introduction:

Electronegativity is a measure of how strongly atoms attract bonding electrons to themselves.

(c)

Interpretation Introduction

Interpretation:

From the given set of elements $\text{C, Se,}\text{B,}\text{Sn,}\text{Cl}$ the element which is the best electrical conductor has to be identified.

(d)

Interpretation Introduction

Interpretation:

From the given set of elements $\text{C, Se,}\text{B,}\text{Sn,}\text{Cl}$ the element which has maximum oxidation state of $+6$ has to be identified.

Concept introduction:

Oxidation number:

Oxidation number means the total number of electron that an atom either gains or loses in order to form a chemical bond with another atom.

(e)

Interpretation Introduction

Interpretation:

From the given set of elements $\text{C, Se,}\text{B,}\text{Sn,}\text{Cl}$ the element which forms hydride with the empirical formula ${\text{XH}}_{\text{3}}$ has to be identified.
