substances
Elements: Pure substance. Made up of only itself (Ex: Oxygen).
Compound: A substance made up of two or more elements that are chemically combined (Ex. Water- dihydrogenmonoxide= H2O).
Mixture: Combination of substances (substances can be elements, compounds, or both). These substances are NOTchemically combined, which means that mixtures are differentfrom compounds.
compounds are made of elements, actually they are elements connected with some kind of bond (covalent, ionic...)
elements are elementary substances, and all substances are made of them (unless you want to split an atom :D).
elements are made of atoms which are very small in size. There is 92 natural elements, and around 15-20 artificial elements.
on the other hand there are thousands, tens of thousands compounds, maybe even more.
Elements are single units that form compounds. Compounds are substances made of elements.
Matter?
Compounds can be broken down into smaller components, but elements cannot be broken down any further.
substances
the noble gases
They are called compounds.
Compounds are one or more elements combined to make a compound. Like H2o is oxygen and hydrogen combined.
There Are No Other Elements or Compounds And Mixtures
Copper, Silver, and Gold occur as elements instead of compounds.
The elements and compounds to the right of the equations are called products.
These compounds are called "hydrocarbons".
Mixture.
Noble gases
ReactivityThe ease and speed with which an element combines with other elements and compounds is called the "reactivity" of the element.
Atoms of different elements can " stick together " ( making compounds ) via elements sharing or trading arrangements called
Chemical compounds are formed from chemical elements.
oxides
It is called a Chemical reaction.
