Introduction About Elements and Compounds:
A compound is a substance formed when two or more elements are chemically joined. Water, salt, and sugar are examples of compounds. When the elements are joined, the atoms lose their individual properties and have different properties from the elements they are composed of.To know more about Elements and Compounds,watch Elements and Compounds Video to learn more .
Elements and Compounds:
Elements are substances that cannot be separated into simpler substances. Salt is made up of the elements sodium and chloride. Water is made up of the elements hydrogen and oxygen. A compound is a substance formed when two or more elements are chemically joined. Water, salt, and sugar are examples of compounds. When the elements are joined, the atoms lose their individual properties and have different properties from the elements they are composed of. A chemical formula is used a quick way to show the composition of compounds. Letters, numbers, and symbols are used to represent elements and the number of elements in each compound.
An ELEMENT is a substance which cannot be broken down into simpler component substances. An ATOM is the smallest possible unit of an element. Atoms are extremely small so any visible specimen of an element contains enormous numbers of atoms. Each element’s atoms are unique to that element.A COMPOUND differs from an element in that an element contains only a single type of atom while a compound consists of smallest units which contain at least two different types of atom (i.e. atoms of at least two different elements) joined together by chemical bonds. Compounds always contain atoms of their constituent elements in the same numerical ratio regardless of how the compound was prepared.
