Elements are anything on the Periodic Table.
compunds are two elements combined.
mixtures are three or more elements that can be seperated.
atoms are a part of an element compound or mixture. example..
pb (Lead) 1 element 1 atom
H20 (water) 3 atoms 1xhydrogeon 2xoxygen
compound
In a compound chemical elements are linked by chemical bonds.
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.
No, its the opposite. Compounds have fixed ratios, think of H20, while mixtures can vary. You can make many types of mixtures out of the same things. Because of bonding compounds have fixed ratios.
No, elements in a compound are not always present in the same proportions. The ratio of elements in a compound is determined by its chemical formula.
A compound is chemically bonded unlike mixtures and compounds you can't take the elements apart, mixtures you can.

Elements, mixtures, etc
no they do not
They were introduced to help people describe our world.
Metallic compounds are homogeneous mixtures. They are mixtures of different metal elements. But particles of each metal cannot be seen separately.
Yes look at air it has oxygen and nitrogen(elements) and carbon dioxide(compound)
the properties of a compound are not the same as the elements that form them.
