They are:
Carbon, hydrogen, nitrogen and oxygen are the four most common. I believe phosphorous and sulfur are the next most common.
A marble is not an element. It is a mixture of a variety of compounds which are in turn made up of several elements. The identities of those elements and compounds depends on the marble. Common elements include silicon, oxygen, and boron.
Elements and compounds are related in sense that elements bond together chemically to make compounds. A compound can be broken down into pure elements. Example. Water (H20), Is Hydrogen (pure element) and Oxygen (also pure element) bonded together to form a compound (H20). However, while a compound can be broken down into its simple elements, an element cannot be broken down. It is said that an element is the purest whole form. --- Some common substances include both elements (pure elements) and compounds. Air, for example, contains elements such as nitrogen and oxygen, and also compounds such as carbon dioxide (CO2), which is made from carbon and oxygen.
substances
Very important, out body is made of compounds, which are in turn made of elements.
Carbon, hydrogen, nitrogen and oxygen are the four most common. I believe phosphorous and sulfur are the next most common.
Chemical compounds are formed from chemical elements.
All compounds are made of two or more elements.
No, the other way around. Kind of. Elements are made of compounds of atoms.
Matter include and others entities than elements and compounds.
Compounds are made of elements. Elements are the smallest units of the compounds. Elements are bond to make compounds.
Compounds.
Elements are single, however compounds are made up of two or more elements.
Two or more elements.
A marble is not an element. It is a mixture of a variety of compounds which are in turn made up of several elements. The identities of those elements and compounds depends on the marble. Common elements include silicon, oxygen, and boron.
Elements are listed in the Periodic Table of Elements. Compounds are not listed there because they are not elements they are compounds. An element is a substance made up of one type of atom, compounds are formed from combinations of different elements.
Yes, chemical compounds are made up of elements combined together.
