In an element, all the atoms are of the same type. That is, they all have the same number of protons in their nuclei (atomic number). A sample of an element cannot be separated into two or more components that have different chemical properties . (Isotopes don't count because they don't have different chemical properties.
In a compound, atoms of different elements are connected into molecules or arrayed into crystals, but each molecule has the same number of atoms of each type in the same arrangement, and each crystal has the same types of atoms arrayed in the same pattern. A compound can only be separated into two or more components with different properties by a process that involves a chemical change.
In a mixture there are pieces or molecules of several different compounds, or uncombined atoms of different elements, which can be separated from one another by means that do not involve chemical change.

What do elements compounds and mixtures have in common?
The commonalities that elements, compounds, and mixtures all have in common is that they all contain atoms. Even though they all contain atoms, the number of atoms vary in each of them.
Is Silver Oxide an element compound homogeneous mixture or heterogeneous mixture?
Silver oxide is a compound, which is a chemical substance composed of two or more elements in fixed proportions. It is not a mixture, as it does not have varying composition like mixtures do, and it does not contain only one type of atom like elements do.
Is a quarter made up of an element or a compound?
A quarter is actually made up of two elements, nickel and copper. This is not a compound, it is a mixture (mixtures of metals are called alloys).
Is rock a compound or an element?
Rock is not a compound or an element. Rocks are made up of minerals, which are compounds or mixtures of elements. Minerals are naturally occurring inorganic substances with a specific chemical composition and atomic structure.
Is a compound simply a mixture of two or more elements?
No. A mixture of elements would just be a mixture. The components of the mixture would remain chemically distinct. In a compound the elements are chemically bound to one another and behave as a single substance with its own set of properties. As an example, water (H2O) is a compound of hydrogen and oxygen that is liquid at room temperature. If you simply mix together hydrogen and oxygen, all you have is a mixture of gasses that will explode if exposed to a spark. This reaction will produce water vapor.
What are two ways in which mixtures differ from compound?
A compound is chemically bonded unlike mixtures and compounds you can't take the elements apart, mixtures you can.
What are two ways in which mixtures are differ from compound?
A compound is chemically bonded unlike mixtures and compounds you can't take the elements apart, mixtures you can.
Is iron sulfide compounds elements or mixtures?
compound
What elements compound and mixtures that makes sand?
silicon and oxygen
How is compound made from hydrogen and oxygen different from these mixtures of these two elements?
In a compound chemical elements are linked by chemical bonds.
What do elements compounds and mixtures and in common?
A compound is two or more elements that are chemically combined and is homogeneous. An example of a compound/homogeneous is Sodium Chloride (NaCl.) A mixture is a heterogeneous, which is the opposite of a compound but otherwise I do not know much about mixtures.
What two things bond to form a compound?
Elements, mixtures, etc
Why were elements compound and mixtures introduced?
They were introduced to help people describe our world.
Are metallic compound homogeneous or heterogeneous?
Metallic compounds are homogeneous mixtures. They are mixtures of different metal elements. But particles of each metal cannot be seen separately.
Can mixtures be made of elements and compounds?
Yes look at air it has oxygen and nitrogen(elements) and carbon dioxide(compound)
Elements are mixtures of What?
Elements are not mixtures of anything. An element contains only atoms of that elements and nothing else. A compound contains two or more elements which have been chemically combined to create a new substance with different chemical and physical properties to the elements from which it was formed.
What is the proper sequence to increase the complexity of compound mixtures and elements?
You think probable to chemical reactions.
