Ответ:
The compound may have properties that are very different from those of the elements
Explanation:
The formation of a compound from its constituent elements is a chemical reaction or chemical change. After the chemical reaction takes place, the properties of the compound formed may be markedly different from that of its constituent elements due to the chemical change that has taken place.
Hence the properties of compounds may not be the same as those of their constituent elements.
