Question

Any body can say why metal react with acid and non metal do not react with acid

Answer 1

Answer:

Reactivity

Step-by-step explanation:

Metals are electropositive in nature , they are happy to loose electrons.

Acids have $H^{+}$ ions so they want electrons.

So metal react with acids fulfill their needs.

But non-metals are electronegative in nature, so they can't fulfill acid need because non-metals also needs electrons so as acids.

So non-metals not react with acids.  

Answer 2

Generally, the non-metals do not react with dilute acids. This is because when a substance reacts with acids, it provides electrons to the H+ ions produced by the acids. Non-metals are themselves acceptors of electrons so there is no way they can donate electrons to the hydrogen ion of the acid. Hence, non-metals in general do not react with dilute acids.
