Chapter 1, Problem 1.43SP

Interpretation Introduction

Interpretation:

The nature of the given elements has to be identified.

Concept introduction:

Let us consider the periodic table those elements on the left side of the zigzag line running from $\text{Boron }\left(\text{B}\right)\text{ to Astatine }\left(\text{At}\right)$ are metals and it’s highly reactive with water.

Those elements to the right of the line are non-metals and less reactive nature.

Semimetal is a material that has an electrical conductivity intermediate among that of a metal and that of an insulator. $\text{Si, Ge, and Sn}$ are semiconductors.
