Question

Sodium metal reacts violently with water and chlorine is a toxic gas, yet we eat sodium chloride. Why is this possible?1.The properties of compounds are identical to the properties of the elements that form the compounds, and we should not eat sodium chloride because it is toxic.2.The chemical properties of compounds are different from the chemical properties of the elements that form the compounds, but the physical properties of the elements and compound are the same.3.The properties of compounds are different from the properties of the elements that form the compounds.4.The physical properties of compounds are different from the physical properties of the elements that form the compounds, but the chemical properties of the elements and compound are the same.

Answer 1

In this question, we have a situation where we have two elements, that are dangerous for humans, but when we put them together, they end up being beneficial to humans.

The physical properties of the compound will be different from the physical properties of the individual elements, for example, chlorine is a gas, but when it is with sodium, it becomes a solid

The chemical properties will also change, therefore compounds will have a different chemical property compared to the individual element

Therefore the best answer for this question will be number 3
