Solution:concept - Nonmetals are generally observed on the right side of the periodic table. The reactivity of nonmetals depends on their electron acceptor and donor nature.
Nonmetals are electron acceptor elements that accept electrons and form anions. Acids are proton donor species that produce ions. When an acid reacts w h other species, then that ion accepts an electron from that species.
Nonmetals are electron acceptors, that is, when they do not react because when they react with acids, they do not give an electron to the ion.
The reactivity of a species is the ability to react with another species. Since non-metals do not react with acids, we can say that they are non-reactive with acids. Therefore, non-metals do not react with acids.
Hence, the correct option is (4).
