Chapter 6, Problem 31A

Interpretation Introduction

Interpretation:

The properties of metalloids are to be compared to metals and non-metals.

Concept Introduction :

The periodic table is a columnar structure that organizes different elements into groups based on how they behave.The elements in the periodic table of today are ordered according to the periodic law.The elements are organized in the modern periodic table in increasing order of their atomic number.In the periodic table, metals lie on the left side of the periodic table whereas non-metals lie on the right side of the periodic table. Metalloids are placed in between metals and non-metals in the staircase pattern.

Answer to Problem 31A

The characteristics of metalloids are in-between those of metals and non-metals.

Explanation of Solution

Metals are shiny, malleable, ductile, and good conductors of heat and electricity. Non-metals on the other hand are dull, brittle, non-malleable, non-ductile, and poor conductors of heat and electricity.

Some metalloids are shiny like metals and brittle like non-metals. They are semiconductors of electricity.

Thus, the properties of metalloids lie between metals and non-metals.
