Chapter 6.2, Problem 14SSC

Interpretation Introduction

Interpretation:

The reason for elements in same group having similar properties needs to be explained.

Concept introduction:

A periodic table consists 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 blocks in the periodic table such as s, p, d and f block.

Answer to Problem 14SSC

The elements placed in a group usually have similar properties because, they have same number of valence electrons and they also have similar electronic configuration.

Explanation of Solution

Elements in the periodic table are arranged in different groups. Similarly, elements are also classified according to various blocks such as s, p, d and f block. The elements placed in a group usually have similar properties. It is because, they have same number of total valence electrons and hence, they share similar electronic configuration.

Conclusion

The elements placed in a group usually have similar properties. It is because, they have same number of valence electrons and hence, they share similar electronic configuration.
