What is element and compound Grade 7?
Elements are made up of one kind of atom which cannot be broken into simpler substances. Compounds are made up of two or more kinds of atoms(elements), chemically combined in a fixed proportion.
Is water an element?

What is the difference between matter and element?
The term matter refers to anything that occupies space and has mass—in other words, the “stuff” that the universe is made of.

What are some common elements and compounds?
Elements and compounds are the two types of pure substances. Examples of common elements include carbon, nitrogen and hydrogen. They consist of one type of atom and cannot break down into something else. Every pure carbon substance, for example, has the same particles in it. Compounds such as water, salt and sugar are also pure substances.
What is the definition of elements and compounds?
Terms elementAny one of the simplest chemical substances that cannot be changed in a chemical reaction or by any chemical means. compoundA substance made from two or more elements. Consists of a fixed ratio of chemically bonded atoms. chemical bondAny of several attractive forces that serve to bind atoms together to form molecules.
What are elements compounds and mixtures?
An element contains just one type of atom. A compound contains two or more different atoms joined together. A mixture contains two or more different substances that are only physically joined together, not chemically. A mixture can contain both elements and compounds.
