Chapter 6, Problem 30A

(a)

Interpretation Introduction

Interpretation:Given property is to be identified as a property corresponding to metal or non-metal.

Concept introduction:

The periodic table is a columnar structure that organizes different elements into groups based on how they behave. 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.

Answer to Problem 30A

Non-metals

Explanation of Solution

Most of the lighter non-metals are gases at room temperature. For example, hydrogen, fluorine, nitrogen, oxygen, chlorine, etc. are gases at room temperature.

Metals are generally solid. The only metal which occurs in a liquid state at normal temperature is mercury.

Thus, non-metals are gases at room temperature.

Answer to Problem 30A

Non-metal

Explanation of Solution

Being readily broken is a quality of brittleness. It is a property of non-metal.

Answer to Problem 30A

Metal

Explanation of Solution

A material's malleability refers to its ability to be stretched or molded under hammer or roller pressure. It is a property of the metal. For example, gold, silver

Answer to Problem 30A

Non-metal

Explanation of Solution

Non-metals are poor conductors of electricity. Due to the lack of free electrons in the lattice, they are poor heat and electrical conductors.

Answer to Problem 30A

Metal

Explanation of Solution

Metals are shiny and this property makes them useful for making ornaments.

Thus, the shiny property is related to metals.
