Explain how the principle of a displacement reaction is based on the reactivity of metals and non-metals.

Displacement reactions help to predict the reactivity of elements.

As we move down the activity series, the reactivity of metals :

Give three differences between metals and non-metals.

Elements showing properties of both metals and non-metals

Explain with an example how displacement reactions help to distinguish between more reactive and less reactive elements.

Nitrogen is an active non-metal.

The table given below shows the position of element U, V, X, Y and Z Identify most reactive metal and non-metal

What are the major differences between metals and non-metals?

The order of reactivity of alcohols with sodium metal is

The correct order of reactivity in alkali metals is:
