Why is salt, NaCl, relatively harmless even though the elements that compose it, sodium and chlorine, are toxic?

Interpretation Introduction

Interpretation:

The reason behind the statement that “NaCl salt is relatively harmless even though the elements that compose it are toxic in nature” is to be explained.

Concept Introduction:

The chemical reactivity of elements is determined by the element’s electronic configuration. Elements with full outer orbits are the most stable. The elements that do not have full orbits exchange or share electrons with other elements to obtain a stable configuration.

Explanation of Solution

Given information: NaCl is harmless, but the elements that compose it, sodium and chlorine are toxic.

Chlorine is reactive because it has seven valence electrons, and can accept one electron to attain a stable configuration. Sodium is also reactive because it has one valence electron. Sodium can transfer this electron to another element to get a stable configuration...
