there are many substances like: methanol, ethanol, sugar.
There are two types of pure substances these are: Element and Compound
Elements:-no physical or chemical means can further change it to simpler form.
-this can be classified into:
a.metal
-have luster
-malleable/ ductile
-conductor
-hard
b.non-metal
-dull
-brittle
-insulators
-soft
c. metalloid
-dull/luster
-malleable/ductile
-semi-conductors
-soft/ hard
Compound-is a substance which can broken down into simpler substances by ordinary chemical means.
they're two types of substances:
Elements- (made of only one kind of an atom) such as Carbon, oxygen, nitroge, sulfur, iron, potassium,etc...
these are located on the Periodic Table
compunds- made from chemical combinations of 2 or more elements. An example would be Sodium Chloride, NaCl
composed of Sodium and Chlorine to make our famous known Tablesalt.

Two neutral substances would include pure water and most types of salts.
There is no such thing. An element IS a pure substance.
Pure substances fall into two categories: elements or compounds, both of which have constant compositions. H2O is a compound, and therefore a pure substance because its composition does not vary.
Pure substance.
An element is a pure substance with only one type of atom. Any pure substance - oxygen, carbon, aluminium. It cannot have two different types of atoms, like carbon dioxide, which has carbon atoms and oxygen atoms.
The two primary types of homogeneous matter are elements and compounds. Homogeneous matter is a substance that has uniform properties and compositions.
