How many main states of matter are there?
What are three? (Solid, liquid, and gas)
What is the smallest part of an element?
What is an atom?
This is a physical combination of two or more substances where each keeps its own properties.
What is a mixture?
This type of change does not form a new substance and can often be reversed.

NAME THREE MAIN STATES OF MATTER.
WHAT ARE SOLID, LIQUID AND GAS
Which state of matter takes the shape of its container but has a fixed volume?
What is a liquid?
What is the center of an atom called?

This is formed when two or more elements chemically combine in a fixed ratio.
What is a compound?
Burning wood is an example of this kind of change.

Can gases be compressed (squeezed into a smaller space)? Why or why not?
What is yes, because their particles are far apart?
In which state are the particles packed tightly and only vibrate in place?
What is a solid?
What does the atomic number of an element tell us? What does the atomic number of an element tell us?
What is the number of protons in an atom?
Unlike mixtures, these substances cannot be separated by physical means because they are chemically bonded.
What are compounds?
Rust forming on iron is an example of this kind of change.
