EVERYDAY SCIENCE

Detailed explanation-1: -A compound always has the same elements in the same proportions. The properties of compounds are different from the properties of the elements that form them sometimes very different. That s because elements in a compound combine and become an entirely different substance with its own unique properties.

Detailed explanation-2: -A compound is a unique substance that forms when two or more elements combine chemically. A compound always consists of the same elements in the same ratio. If the same elements combine in different ratios, they form different compounds.

Detailed explanation-3: -The properties of an element do change when that element combines with other elements to form compounds. There are only 118 known elements which combine to make everything in the universe. If you think about that, you’ll see that the properties of the element must change depending upon the compound it is in.

Detailed explanation-4: -In chemistry, a compound is a substance made up of two or more different chemical elements combined in a fixed ratio. When the elements come together, they react with each other and form chemical bonds that are difficult to break. These bonds form as a result of sharing or exchanging electrons between atoms.

Detailed explanation-5: -Answer: When elements combine to form compounds, their individual properties are lost. In comparison, elements retain some (or many) of their property when they are mixed to form a mixture.
