Do elements combined lose their special properties

Answer 1

When elements are chemically combined to form compounds, they do not lose their special properties. Instead, the new compound will have its own unique set of properties that are a combination of the properties of the individual elements. For example, when sodium (a highly reactive metal) combines with chlorine (a toxic gas), it forms sodium chloride, which is a stable and non-reactive compound commonly known as table salt. In this case, the special properties of sodium and chlorine are retained in the compound, but the compound itself has different properties than the individual elements.
