Textbook Problem

Write the formula for each of the following

  1. (a) hydrogen telluride
  2. (b) sodium arsenate
  3. (c) selenium hexachloride
  4. (d) perbromic acid

(a)

Interpretation Introduction

Interpretation:  The formula of given compound hydrogen telluride has to be stated.

Concept introduction: The p-block elements form molecular compounds in which the central atom has highest oxidation number. The highest oxidation number is always equal to the group number that the element has in the periodic table. Thus the oxidation number is determined by the position of the element in the periodic table.

The elements belonging to the same group of periodic table have same number of electrons in their valence shell. Thus, their physical and chemical properties are also similar.

These elements can exist in similar oxidation state due to same number of valence electrons in the outermost shell. Hence, the elements of same group form compounds with same formula.

Explanation

The elements that belong to the same family and are placed in the same group of periodic table have similar chemical properties. Thus, tellurium resembles oxygen chemically and forms compound with similar chemical formula. This is attributed to the fact that they have same number of valence electrons in their outermost shell.

The electronic configuration of oxygen is: 1s22s22p4

The electronic configuration of tellurium is:

(b)

Interpretation Introduction

Interpretation:  The formula of given compound sodium arsenate has to be stated.

Concept introduction: The p-block elements form molecular compounds in which the central atom has highest oxidation number. The highest oxidation number is always equal to the group number that the element has in the periodic table. Thus the oxidation number is determined by the position of the element in the periodic table.

The elements belonging to the same group of periodic table have same number of electrons in their valence shell. Thus, their physical and chemical properties are also similar.

These elements can exist in similar oxidation state due to same number of valence electrons in the outermost shell. Hence, the elements of same group form compounds with same formula.

(c)

Interpretation Introduction

Interpretation:  The formula of given compound selenim hexachloride has to be stated.

Concept introduction: The p-block elements form molecular compounds in which the central atom has highest oxidation number. The highest oxidation number is always equal to the group number that the element has in the periodic table. Thus the oxidation number is determined by the position of the element in the periodic table.

The elements belonging to the same group of periodic table have same number of electrons in their valence shell. Thus, their physical and chemical properties are also similar.

These elements can exist in similar oxidation state due to same number of valence electrons in the outermost shell. Hence, the elements of same group form compounds with same formula.

(d)

Interpretation Introduction

Interpretation:  The formula of given compound perbromic acid has to be stated.

Concept introduction: The p-block elements form molecular compounds in which the central atom has highest oxidation number. The highest oxidation number is always equal to the group number that the element has in the periodic table. Thus the oxidation number is determined by the position of the element in the periodic table.

The elements belonging to the same group of periodic table have same number of electrons in their valence shell. Thus, their physical and chemical properties are also similar.
