States of Matter
A change from liquid to solid is called...
Freezing
This is a measure of how much matter is present.
What is mass?
The subatomic particles (the parts of an atom.)
What are protons, neutrons, and electrons.
This is a change in size, shape, or phase only
What is a physical change?
The smallest unit of matter which has properties of a chemical element.
What is an atom?
This state is the most dense.
What is solid?
This is a measure of how much space matter takes up.
What is volume?
This is how you find the number of protons
What is the atomic number?
This is a change that forms a new substance
What is a chemical change?
Trail mix is this kind of mixture.
What is heterogenous?
This energy is responsible for changing the state of matter
What is thermal energy?
This is a measure of how much matter is in a given space.
What is density?
This is how you find the number of neutrons in an atom
What is subtract the atomic number from the mass number?
Iodine turning black on starch was this kind of change
What is chemical?
What properties do most metals have?
What are shiny, conductors of heat and electricity, and solid?
The change directly from solid to gas
What is sublimation?
This method is used to calculate the volume of unusually shaped objects.
These particles are found in the nucleus of an atom.
What protons and neutrons?
Sugar dissolving in tea is this kind of change
What is physical?
This element is named for the "Mother of Radioactivity" (*hint - we watched a video about her....)
What is Curium? (Named for Marie Curie)
This is a 4th state of matter.
What is plasma?
Mass does not change based on location. But this phenomenon can change the weight of an object.
What is gravity?
Atoms always have the same number of these
What are electrons and protons?
These are ways to tell that a chemical change has occurred
What are color change, gas is produced (smell or bubbles or fizz), a solid is formed, bright light or temperature change, etc?
This column is known for having full valence shells (full outer shell of electrons)
What are the Noble Gasses?
