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
What else can I help you with?
Is iron sulfide compounds elements or mixtures?
compound
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.
Do compounds usually have variable ratios where as mixtures usually have fixed ratios?
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.
Are elements that make up a compound always present in the same proportions?
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.
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?

What two things bond to form a compound?
Elements, mixtures, etc
Do compound and mixtures have the same freezing point?
no they do not
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)
Are the properties of a compound the same of the properties of its elements?
the properties of a compound are not the same as the elements that form them.
