Matter & Properties
This is anything that has mass and takes up space.
What is matter?
This is the smallest unit of an element that retains its identity.
What is an atom?
This chart organizes the chemical elements.
What is the Periodic Table?
This is what atoms may form when they bond together.
What is a molecule?
This state of matter has a definite shape and volume.
What is a solid?
This scientific tool measures the mass of an object.
What is a balance?
This is the center of an atom.
What is the nucleus?
This is the chemical symbol for oxygen.
What is O?
This is the number of atoms in one O₂ molecule.
What is two?
This state of matter has a definite volume but takes the shape of its container.
What is a liquid?
Color, texture, shape, and shininess are examples of these.
What are physical properties?
This subatomic particle has a negative charge.
What is an electron?
This element is represented by the symbol H.
What is hydrogen?

What is He?
This is the number of different elements found in water, H₂O.
There are two elements found in this molecule.
In a solid, particles are packed tightly and do this in fixed positions.
What is they vibrate packed tightly together?
Two objects have the same volume but different masses because this property differs.
What is density?
These two subatomic particles are found together in the nucleus.
What are protons and neutrons?
This term describes a substance made of only one kind of atom.
What is an element?
This formula represents one carbon atom joined to two oxygen atoms.
What is CO₂?
During melting, a substance changes from this state of matter into a liquid.
