what does the statment"the properties of salt are diffrent from the properts of the elements that go into making them"mean? i don't get what they are asking.

The statement "the properties of salt are different from the properties of the elements that go into making them" means that the characteristics or qualities of salt (a compound) are not the same as the characteristics of the individual elements (sodium and chlorine) that combine to form it. In other words, when sodium and chlorine chemically react to form salt, the resulting compound (salt) possesses unique properties that are distinct from those of its constituent elements.

To understand this concept better, let's break it down step by step:

1. Elements: Elements are the most fundamental forms of matter; they cannot be broken down into simpler substances by chemical means. Examples of elements include sodium (Na) and chlorine (Cl).

2. Properties of elements: Each element has its own unique set of properties that determine its behavior, such as melting point, boiling point, color, density, and reactivity. For instance, sodium is highly reactive and can catch fire when exposed to air, while chlorine is a toxic gas with a strong smell.

3. Compound formation: When elements chemically react, they can combine to form compounds. Salt, or sodium chloride (NaCl), is one such compound.

4. Properties of salt: Once sodium and chlorine react to form salt, the compound possesses distinct properties different from those of its constituent elements. In the case of salt, it is a white crystalline solid, is soluble in water, has a characteristic taste, and is used as a seasoning.

So, the statement you mentioned highlights the fact that the properties of a compound (salt) can be unique and distinct from the properties of the elements that combine to form it (sodium and chlorine).
