Chapter 18.1, Problem 1RQ

Interpretation Introduction

Interpretation: In metal and the non-metal reaction, the substance that is oxidized or reduced needs to be determined.

Concept Introduction: Oxidation-reduction reactions are characterized by a transfer of electrons. The oxidation reaction is caused by losing electrons and reduction is caused by gaining of electrons.

Answer to Problem 1RQ

In a reaction between a metal and the non-metal, metal is oxidized and non-metal is reduced.

Explanation of Solution

Metals are those which tend to give electrons while non-metals tend to gain electrons. The loss of electron results in oxidation and the gain of electrons results in reduction. Hence, metal tends to be oxidized and non-metal tends to be reduced in a reaction between a metal and a non-metal.

Conclusion

An ionic compound is formed when metal combines with non-metal. In this type of reaction, electrons are shifted from the metal to the non-metal.
