Chapter 6.2, Problem 8PP
Interpretation Introduction

(a)

Interpretation:

The group, period and the block of an atom with the configuration [Ne]3s2 without using the periodic table needs to be determined.

Concept introduction:

The horizontal rows of periodic table are termed as periods and the vertical columns are termed as groups. There are 7 periods and 18 groups present in the periodic table. The periodic table has four blocks, s-block, p-block, d-block and f-block.

Answer to Problem 8PP

The element with configuration [Ne]3s2 belongs to 3rd period, 2nd group and s-block of the periodic table.

Explanation of Solution

The electronic configuration of the element is [Ne]3s2. In the electronic configuration, the number of highest energy level indicates the period number. So, in the element [Ne]3s2, 3 indicates the period number. So, the element belongs to 3rd period. For representative element, valence electrons indicate the group number. The number of valence electrons is 2 for the element. So, the group number is 2. As the element is present in group 2, it belongs to s-block of the periodic table.

(b)

Interpretation Introduction

Interpretation:

The group, period and the block of an atom with the configuration [He]2s2 without using the periodic table needs to be determined.

Concept introduction:

The horizontal rows of periodic table are termed as periods and the vertical columns are termed as groups. There are 7 periods and 18 groups present in the periodic table. The periodic table has four blocks, s-block, p-block, d-block and f-block.

Answer to Problem 8PP

The element with configuration [He]2s2 belongs to 2nd period, 2nd group and s-block of the periodic table.

Explanation of Solution

The electronic configuration of the element is [He]2s2. In the electronic configuration, the number of highest energy level indicates the period number. So, in the element [He]2s2, 2 indicate the period number. So, the element belongs to 2nd period. For representative element, valence electrons indicate the group number. The number of valence electrons is 2 for the element. So, the group number for the element is 2. As the element is present in group 2, it belongs to s-block of the periodic table.

(c)

Interpretation Introduction

Interpretation:

The group, period and the block of an atom with the configuration [Kr]5s24d105p5 without using the periodic table needs to be determined.

Concept introduction:

The horizontal rows of periodic table are termed as periods and the vertical columns are termed as groups. There are 7 periods and 18 groups present in the periodic table. The periodic table has four blocks, s-block, p-block, d-block and f-block.

Answer to Problem 8PP

The element with configuration [Kr]5s24d105p5 belongs to 5th period, 17th group and p-block of the periodic table.

Explanation of Solution

The electronic configuration of the element is [Kr]5s24d105p5. In the electronic configuration, the number of highest energy level indicates the period number. So, in the element [Kr]5s24d105p5, the number of highest energy level is 5 which indicate the period number. So, the element belongs to 5th period. For representative element, valence electrons indicate the group number. The number of valence electrons is 7 for the element. So, the group number for the element is 17. As the element is present in group 7, it belongs to p-block of the periodic table.
