The particle diagram that represents a mixture of three substances is seen in Option 2.
A particle is a small portion of a matter that has both physical and chemical properties.
In inorganic chemistry, a substance refers to a form of matter ( usually particles) that can not be separated by ordinary physical means but by a chemical process.
It can either be:
- an element or a compound.
From the information given, we have:
- an atom of one element
- an atom of a different element
Option 1, 3, and 4 show a particle diagram representing a mixture of only two substances but Only Option 2 shows a particle diagram representing a mixture of three substances.
Therefore, we can conclude that the particle diagram that represents a mixture of three substances is seen in Option 2.
