Chapter 6.2, Problem 12SSC

Interpretation Introduction

(a)

Interpretation:

The block to which the valence electron configuration s²p⁴belongs needs to be determined.

Concept introduction:

A periodic table consist of groups and periods. The horizontal rows are termed as periods and the vertical rows are termed as groups. The elements with similar properties are placed together in a group. Each period has different energy levels. Elements are also arranged according to various block in the periodic table such as s, p, d and f block.

Answer to Problem 12SSC

s²p⁴configuration belong to the p-block.

Explanation of Solution

Oxygen has the electronic configuration [He]s²p⁴. The element oxygen belongs to group 16 of the periodic table. Group 16 belong to the p-block. Hence, s²p⁴configuration belongs to the p-block.

(b)

Interpretation Introduction

Interpretation:

The block to which the valence electron configuration s¹belongs needs to be determined.

Concept introduction:

A periodic table consist of groups and periods. The horizontal rows are termed as periods and the vertical rows are termed as groups. The elements with similar properties are placed together in a group. Each period has different energy levels. Elements are also arranged according to various block in the periodic table such as s, p, d and f block.

Answer to Problem 12SSC

s¹configuration belong to the s-block.

Explanation of Solution

Hydrogen has the electronic configuration s¹. The element hydrogen belongs to group 1(A) of the periodic table. Group1(A) belong to the s-block. Hence, s¹configuration belongs to the s-block.

(c)

Interpretation Introduction

Interpretation:

The block to which the valence electron configuration s²d¹belongs needs to be determined.

Concept introduction:

A periodic table consist of groups and periods. The horizontal rows are termed as periods and the vertical rows are termed as groups. The elements with similar properties are placed together in a group. Each period has different energy levels. Elements are also arranged according to various block in the periodic table such as s, p, d and f block.

Answer to Problem 12SSC

s²d¹configuration belong to the d-block.

Explanation of Solution

Scandium has the electronic configuration [Ar] 3d¹4s². The element Scandium belongs to group 3 of the periodic table. Group 3 belong to the d-block. Hence, s²d¹configuration belongs to the d-block.

(d)

Interpretation Introduction

Interpretation:

The block to which the valence electron configuration s²p¹belongs needs to be determined.

Concept introduction:

A periodic table consist of groups and periods. The horizontal rows are termed as groups and the vertical rows are termed as periods. The elements with similar properties are placed together in a group. Each period has different energy levels.
