100
What does the Atomic Model show? (Use scientific language)
The atomic model shows the subatomic particles in an atom.
100
What holds atoms together?
A chemical bond.
200
What is matter
Anything that has mass and takes up space
200
What are the two types of molecules?
The two types are elements and compounds.
200
How fast do gasses move?
Gasses move very fast and spread out.
200
What are the three sub atomic particles in an atom
Protons, Neutrons, and electrons
200
What is Chemistry?
Chemistry is the study of matter
300
List 5 examples of matter
Table, Chair, pencil, Air, paper
300
How small can a molecule be?
A molecules has to be two or more atoms.
300
How do you increase the movement of the particles?
You add heat.
300
Where are electrons located and what are their charge?
Electrons are located on the outside of an atom and have a negative charge.
300
What are the three states of matter, and how do you get from one state to the next?
Solid, liquid and gas. You get to another state of matter by adding or removing heat.
400
What would happen if there were no atoms
There would be nothing but heat and light
400
What makes an element different from a compound?
Elements have the same type of atoms where compounds have different types of atoms.
400
What is the format for writing a hypothesis? Write a hypothesis about time studying and grade on test.
If, then If I spend more time studying then I will do better on my test because I will know more.
400
What are the two sub atomic particles located in the nucleus of an atom and what are their electrical charges?
Protons have a positive charge and Neutrons have no charge.
400
What happens to the number of chemical bonds when you go from a solid to a liquid
They stay the same, they just move closer together.
500
How do you get from matter down to one atom?
You break matter down into smaller pieces that can no longer be broken
500
What makes an element different from a compound?
Elements have the same type of atoms where compounds have different types of atoms.
500
How does the temperature of a substance affect its particle speed.
As the temperature increases, the speed increases. As the temperature decreases, the speed increases.
500
What makes one atoms different from another.
The number of protons. (I will accept the number of sub atomic particles)
500
Why is the atomic model the foundation for Chemistry?
Without a diagram of an atom, scientist can not know the properties of an atoms and its particles. Since atoms are the basic units of matter and atoms make up matter, it means that they could not fully study Chemistry.
