Question

Give reasons for the following
i) Non-metals in general do not displace hydrogen from dilute acids.
ii) Metals conduct electricity.​

Answer 1

Answer:

Explanation:

1.Metals have a tendency to lose electrons. These electrons, which are readily lost by reactive metals like sodium, potassium etc are accepted by hydrogen ions of the acids, reducing them to hydrogen gas (H. However, non-metals do not lose electrons readily, because of which they do not displace hydrogen from acids.

2.Metals conduct electricity because the attraction of the nucleus on the valence electrons is minimum. Hence, these electrons can move freely.
